Description

  The present invention relates to a control device and a control method for controlling acceleration of a vehicle when the vehicle starts.

  As an accident that occurs while driving a vehicle, there is an accident in which a stopped vehicle suddenly accelerates and collides with a child or an elderly person in the blind spot of the vehicle. Further, the fuel consumed when the stopped vehicle is accelerated rapidly is larger than the fuel consumed when the vehicle is gradually accelerated.

  In order to prevent a collision accident due to a sudden start of the vehicle and to reduce fuel consumed when the vehicle starts, it is necessary to prevent the stopped vehicle from suddenly accelerating.

  Patent Document 1 discloses a control device that prevents excessive depression of an accelerator pedal of a vehicle. The control device described in Patent Document 1 is mounted on a vehicle, controls a load generated when the accelerator pedal of the vehicle is depressed, and increases the load when the amount of depression of the accelerator pedal exceeds a threshold value. For this reason, when the amount of depression of the accelerator pedal exceeds the threshold value, in order to increase the depression amount by a predetermined amount, the accelerator pedal must be depressed with a force stronger than the force of depressing the accelerator pedal before the depression amount exceeds the threshold value. Therefore, the vehicle is difficult to accelerate suddenly.

JP 2010-52719 A

  However, the control device described in Patent Document 1 is configured such that the acceleration of the vehicle increases as the amount of depression of the accelerator pedal increases. Therefore, if the driver accidentally depresses the accelerator pedal strongly, There is a possibility that the vehicle suddenly accelerates, and the sudden acceleration of the stopped vehicle is not sufficiently prevented. When the vehicle suddenly accelerates in this way, the vehicle may cause a collision accident with a child or an elderly person in the blind spot of the vehicle, and fuel is wasted.

  The present invention has been made in view of such circumstances, and an object of the present invention is to prevent sudden acceleration of a stopped vehicle so that the vehicle can be started safely and consumed when the vehicle is started. It is an object of the present invention to provide a control device and a control method that use less fuel.

  The control device according to the present invention is a control device for controlling the acceleration of a vehicle, a vehicle speed information acquisition means for acquiring vehicle speed information indicating the speed of the vehicle, and a step for determining whether or not an accelerator pedal of the vehicle is depressed. When it is determined that the speed indicated by the vehicle speed information acquired by the determination means and the vehicle speed information acquisition means is zero, and the depression determination means is depressed, the vehicle has a constant acceleration regardless of the amount of depression of the accelerator pedal. Accelerating means for accelerating the movement.

  The control device according to the present invention is characterized by comprising stop means for stopping acceleration by the acceleration means when the speed indicated by the vehicle speed information acquired by the vehicle speed information acquisition means is greater than or equal to a threshold value.

  According to the control device of the present invention, a depression amount information acquisition unit that acquires depression amount information indicating the depression amount of the accelerator pedal, and a depression amount indicated by the depression amount information acquired by the depression amount information acquisition unit And determining means for determining the threshold value so as to be larger or smaller.

  The control device according to the present invention determines position information acquisition means for acquiring position information indicating the position of the vehicle, and whether or not the position information acquired by the position information acquisition means indicates a position within a specific range. Position determining means, wherein the acceleration means determines that the speed indicated by the vehicle speed information acquired by the vehicle speed information acquiring means is zero, the step determining means is depressed, and the position determining means When it is determined that a position within a specific range is indicated, the vehicle is accelerated at the constant acceleration.

  The control method according to the present invention is a control method for controlling acceleration of a vehicle, acquires vehicle speed information indicating the speed of the vehicle, determines whether or not an accelerator pedal of the vehicle is depressed, and the acquired vehicle speed information is When it is determined that the vehicle speed is zero and the accelerator pedal is depressed, the vehicle is accelerated at a constant acceleration regardless of the amount of depression of the accelerator pedal.

  In the control device and the control method according to the present invention, vehicle speed information indicating the vehicle speed, that is, the vehicle speed is acquired. When it is determined that the speed indicated by the acquired vehicle speed information is zero and the accelerator pedal of the vehicle is depressed, the vehicle is accelerated at a constant acceleration regardless of the depression amount of the accelerator pedal.

  When the vehicle is started by depressing the accelerator pedal of the vehicle, the vehicle is accelerated at a constant acceleration regardless of the amount of depression of the accelerator pedal, so that sudden acceleration of the stopped vehicle is prevented and the vehicle starts safely. To do. Furthermore, since the vehicle does not accelerate suddenly, less fuel is consumed when the vehicle starts.

  In the control device according to the present invention, when the speed indicated by the acquired vehicle speed information is equal to or greater than the threshold, the acceleration of the vehicle at a constant acceleration is stopped. The vehicle speed increases due to acceleration at a constant acceleration, and after the start of the vehicle exceeds a threshold value, for example, 40 km / h, the acceleration is adjusted according to the amount of depression of the accelerator pedal, and the amount of depression of the accelerator pedal is adjusted. The vehicle is accelerated at an acceleration in accordance with.

  In the control device according to the present invention, the depression amount information indicating the depression amount of the accelerator pedal is acquired, and the threshold value is determined so as to become large or small according to the depression amount indicated by the acquired depression amount information. Therefore, since the vehicle speed when the acceleration of the vehicle at a constant acceleration is completed corresponds to the amount of depression of the accelerator pedal, the amount of depression of the accelerator pedal is reduced from the driving of the vehicle accelerating at a certain acceleration. Accordingly, the vehicle is smoothly shifted to driving in which the acceleration is adjusted to be large or small.

  In the control device according to the present invention, position information indicating the position of the vehicle is acquired, and it is determined whether or not the acquired position information indicates a position within a specific range. When it is determined that the speed indicated by the acquired vehicle speed information is zero and the accelerator pedal is depressed, and further, when it is determined that the acquired position information indicates a position within a specific range, the vehicle is moved at a constant acceleration. To accelerate.

  When starting a vehicle located on a highway or a side road of a general road close to the junction with the main road, it may be necessary to accelerate the vehicle rapidly. In the present invention, when the vehicle speed is zero and the accelerator pedal is depressed, the position of the vehicle indicated by the acquired position information is in a specific range, for example, a general road excluding a side road close to a junction with the main road The vehicle is accelerated at a constant acceleration. Therefore, when the vehicle is out of a specific range, that is, a position that requires rapid acceleration of the vehicle, the vehicle is not accelerated at a constant acceleration, and the driver depresses the accelerator pedal deeply. This makes it possible to perform rapid acceleration of the vehicle. Thereby, the driver can drive the vehicle appropriately.

  According to the present invention, when the accelerator pedal of the stopped vehicle is depressed, the vehicle is accelerated at a constant acceleration regardless of the amount of depression of the accelerator pedal. The vehicle can be started immediately, and less fuel is consumed when the vehicle is started.

  The relay device 1 is, for example, a central gateway in which control data and various types of information for each bus are concentrated. The relay device 1 includes communication units 10a and 10b, a storage unit 11, and a control unit 12. The control unit 12 is individually connected to the communication units 10a and 10b and the storage unit 11 via a common bus. The communication units 10a and 10b are connected to the buses 2a and 2b, respectively.

  The control unit 12 uses a CPU (Central Processing Unit). The storage unit 11 uses a nonvolatile memory such as a flash memory or an EEPROM (Electrically Erasable and Programmable Read Only Memory), and stores a control program that is read and executed by the control unit 12. The control unit 12 executes various processes based on the control program.

  Each of the communication units 10a and 10b acquires control data and various information from the buses 2a and 2b, and outputs the acquired control data and various information to the control unit 12. Each of the communication units 10a and 10b outputs control data and various types of information to the buses 2a and 2b in accordance with instructions from the control unit 12.

  The control unit 12 further controls the engine ECU 3 and the transmission from the communication unit 10a based on the vehicle speed information and the depression amount information acquired from the bus 2a by the communication unit 10a and the position information acquired from the bus 2b by the communication unit 10b. By outputting an acceleration instruction or a stop instruction to the ECU 4, the acceleration of the vehicle when the stopped vehicle accelerates is controlled.

  The acceleration control performed by the control unit 12 will be described in detail below. FIG. 2 is a flowchart showing acceleration control processing performed by the control unit 12. First, the control unit 12 causes the communication unit 10a to acquire vehicle speed information from the bus 2a (step S1), and determines whether or not the vehicle speed indicated by the vehicle speed information acquired by the communication unit 10a is zero (step S2). The communication unit 10a functions as vehicle speed information acquisition means.

  When it is determined that the vehicle speed exceeds zero (step S2: NO), the control unit 12 returns the process to step S1 and waits until the vehicle speed becomes zero. When it is determined that the vehicle speed is zero, that is, the vehicle is stopped (step S2: YES), the control unit 12 causes the communication unit 10b to acquire position information from the bus 2b (step S3), and the communication unit 10b. It is determined whether or not the acquired position information indicates a position within a specific range (step S4). The communication unit 10b functions as a position information acquisition unit, and the control unit 12 functions as a position determination unit.

  Here, the specific range is a range where it is not necessary to start the vehicle due to sudden acceleration, for example, a general road excluding a side road close to a junction with the main road. A range that requires rapid acceleration of the vehicle when starting the vehicle, for example, a highway or a side road of a general road that is close to the junction with the main road is outside a specific range.

  When it is determined that the position information acquired by the communication unit 10b in step S3 does not indicate a position within a specific range (step S4: NO), the control unit 12 returns the process to step S1 and the vehicle speed is zero. And it waits until a vehicle is located in a specific range. During this standby period, the engine ECU 3 and the transmission ECU 4 adjust the acceleration of the vehicle according to the amount of depression of the accelerator pedal indicated by the depression amount information, and accelerate the vehicle with the adjusted acceleration.

When it is determined that the position information acquired by the communication unit 10b in step S3 indicates a position within a specific range (step S4: YES), the control unit 12 determines whether the accelerator pedal of the vehicle is depressed. (Step S5).
Here, for example, the control unit 12 determines that the accelerator pedal is depressed when the depression amount indicated by the depression amount information acquired by the communication unit 10a from the bus 2a exceeds zero, and the depression acquired by the communication unit 10a. When the depression amount indicated by the amount information is zero, it is determined that the accelerator pedal is not depressed. The control unit 12 also functions as a stepping determination unit.

  When it is determined that the accelerator pedal is not depressed (step S5: NO), the control unit 12 returns the process to step S5 and waits until the accelerator pedal is depressed.

  When it is determined that the accelerator pedal is depressed (step S5: YES), the control unit 12 causes the communication unit 10a to transmit an acceleration instruction to the engine ECU 3 and the transmission ECU 4, thereby making the vehicle constant regardless of the amount of depression of the accelerator pedal. (Step S6). Thereafter, when the depression amount indicated by the depression amount information exceeds zero until the stop instruction is received from the relay device 1, the engine ECU 3 and the transmission ECU 4 accelerate the vehicle at a constant acceleration α. The control unit 12 also functions as acceleration means.

  As described above, the controller 12 indicates that the vehicle speed indicated by the vehicle speed information acquired by the communication unit 10a in step S1 is zero, the position information acquired by the communication unit 10b in step S3 indicates a position within a specific range, And when it determines with the accelerator pedal having been depressed by step S5, a vehicle is accelerated by the fixed acceleration (alpha) irrelevant to the depression amount of an accelerator pedal.

  Therefore, when the vehicle is started by depressing the accelerator pedal of the vehicle located within the specific range, the vehicle is accelerated at a constant acceleration α that is independent of the amount of depression of the accelerator pedal. For this reason, the relay apparatus 1 can start the vehicle safely by preventing sudden acceleration of the stopped vehicle. Furthermore, since the vehicle does not accelerate suddenly, less fuel is consumed when the vehicle starts.

  In addition, when the position of the vehicle indicated by the position information acquired by the communication unit 10b in step S3 is out of a specific range, that is, in a range that requires rapid acceleration of the vehicle, the vehicle is moved at a constant acceleration α. Without acceleration, the driver can perform rapid acceleration of the vehicle by depressing the accelerator pedal deeply. For this reason, the driver can drive the vehicle appropriately.

  After executing step S6, the control unit 12 causes the communication unit 10a to acquire the depression amount information from the bus 2a (step S7), and according to the amount of depression of the accelerator pedal indicated by the depression amount information acquired by the communication unit 10a. The vehicle speed threshold for determining whether or not to stop the acceleration of the vehicle at a constant acceleration α is determined (step S8). The communication unit 10a also functions as a stepping amount information acquisition unit, and the control unit 12 also functions as a determination unit.

  FIG. 3 is an explanatory diagram for explaining a threshold value determination method. In FIG. 3, the accelerator pedal when the amount of depression of the accelerator pedal is zero is indicated by a solid line. When the accelerator pedal is depressed, the accelerator pedal tilts in the direction indicated by the arrow in FIG. 3, and the greater the accelerator pedal depression amount, the greater the accelerator pedal tilts. Three ranges 90, 91, and 92 are set according to the depression amount of the accelerator pedal. The depression amount of the accelerator pedal in the range 91 is larger than the depression amount of the accelerator pedal in the range 90, and the depression amount of the accelerator pedal in the range 92 is larger than the depression amount of the accelerator pedal in the range 91.

  The storage unit 11 stores ranges 90, 91, and 92, which are ranges of accelerator pedal depression amounts, and threshold candidate values corresponding to the ranges 90, 91, and 92, respectively. In step S8, the control unit 12 obtains candidate threshold values corresponding to the range to which the stepping amount indicated by the stepping amount information acquired by the communication unit 10a in step S7 belongs from the storage unit 11 in the ranges 90, 91, and 92. The read candidate value is determined as a threshold value.

  Here, the threshold value corresponding to the range 91 is larger than the threshold value corresponding to the range 90, and the threshold value corresponding to the range 92 is larger than the threshold value corresponding to the range 91. The threshold values corresponding to the ranges 90, 91, and 92 are set to, for example, 20 km / h, 40 km / h, and 60 km / h. Thus, the threshold value is large or small according to the size of the stepping amount indicated by the stepping amount information acquired by the communication unit 10a in step S7.

  After executing step S8, the control unit 12 causes the communication unit 10a to acquire the depression amount information from the bus 2a again (step S9), and whether the depression amount indicated by the depression amount information acquired by the communication unit 10a is zero. It is determined whether or not (step S10). In steps S9 and S10, the control unit 12 transmits an acceleration instruction to each of the engine ECU 3 and the transmission ECU 4 in step S6, and then the depression of the accelerator pedal is stopped due to the vehicle being caught in a traffic jam or the like. It is determined whether or not the amount of depression has become zero.

  When it is determined that the depression amount indicated by the depression amount information exceeds zero (step S10: NO), the control unit 12 causes the communication unit 10a to acquire vehicle speed information from the bus 2a (step S11), and the communication unit 10a It is determined whether or not the vehicle speed indicated by the acquired vehicle speed information is equal to or greater than the threshold value determined in step S8 (step S12).

  When it is determined that the vehicle speed indicated by the vehicle speed information is less than the threshold (step S12: NO), the control unit 12 returns the process to step S9, or the accelerator pedal depression amount becomes zero, or the vehicle speed is equal to or greater than the threshold. Steps S9 to S12 are repeated until During this period, when the accelerator pedal is depressed, the engine ECU 3 and the transmission ECU 4 accelerate the vehicle at a constant acceleration α irrespective of the amount of depression of the accelerator pedal.

  When it is determined that the stepping amount indicated by the stepping amount information acquired in step S9 is zero (step S10: YES), or the vehicle speed indicated by the vehicle speed information acquired in step S12 is greater than or equal to the threshold value. When it determines (step S12: YES), the communication part 10a is made to transmit a stop instruction | indication to engine ECU3 and transmission ECU4, and the acceleration of the vehicle by fixed acceleration (alpha) is stopped (step S13). The control unit 12 also functions as a stopping unit.

  After receiving the stop instruction, the engine ECU 3 and the transmission ECU 4 adjust the acceleration according to the amount of depression of the accelerator pedal indicated by the depression information as described above, and accelerate the vehicle with the adjusted acceleration.

As described above, the threshold is determined so as to be large or small according to the amount of depression indicated by the depression information acquired in step S7. Therefore, since the vehicle speed when the acceleration of the vehicle at a constant acceleration α is completed corresponds to the amount of depression of the accelerator pedal, from the operation of the vehicle accelerating at the constant acceleration α, the amount of depression of the accelerator pedal is reduced. A smooth transition is made to driving of the vehicle in which the acceleration is adjusted to be large or small according to the magnitude.
The control part 12 complete | finishes a process, after performing step S13, and performs step S1 again.

  Note that the control unit 12 determines that the vehicle speed indicated by the vehicle speed information acquired from the bus 2a is zero and the accelerator pedal does not matter whether the position information acquired from the bus 2b indicates a position within a specific range. When the vehicle is depressed, the vehicle may be accelerated at a constant acceleration α that is irrelevant to the depression amount of the accelerator pedal. Even in this case, since the vehicle does not accelerate suddenly, sudden acceleration of the stopped vehicle can be prevented and the vehicle can be started safely, and less fuel is consumed when starting the vehicle. .

  Moreover, the range of the depression amount of the accelerator pedal memorize | stored in the memory | storage part 11 is not limited to three, Two or four or more may be sufficient. Even in this case, candidate values of thresholds corresponding to the respective ranges are stored in the storage unit 11. Further, the storage unit 11 stores an arithmetic expression for calculating a threshold value from the accelerator pedal depression amount, and the control unit 12 includes the depression amount indicated by the depression information acquired by the communication unit 10a in step 7 in the calculation expression. May be substituted to calculate the threshold value.

  Moreover, the control part 12 does not need to determine a threshold value according to the depression amount of the accelerator pedal which the depression amount information acquired from the bus | bath 2a shows, and may always use one threshold value.

  Moreover, the protocol used when the relay apparatus 1, engine ECU3, transmission ECU4, ECU5a, 5a, ... and IOUs 6a, 6a, ... connected to the bus 2a communicate with each other is not limited to the CAN protocol. Similarly, the protocol used when the relay device 1, ECUs 5b, 5b,... And IOUs 6b, 6b,... Connected to the bus 2b communicate with each other is not limited to the CAN protocol. Moreover, the connection form of the relay apparatus 1, engine ECU3, transmission ECU4, ECU5a, 5a, ..., ECU5b, 5b, ..., IOU6a, 6a, ... and IOU6b, 6b, ... is a bus type. It is not limited, and a star type or ring type connection form may be used.

  In this embodiment, the case where the present invention is applied to a relay device has been described as an example. However, devices to which the present invention can be applied are not limited to relay devices. For example, any one of the engine ECU 3, the transmission ECU 4, the ECUs 5a, 5a,...
