Description

Control system and method for whole vehicle entering and exiting of electric vehicle
Technical Field
The invention relates to a control system and a control method, in particular to a control system and a control method for the whole entering and exiting of an electric automobile.
Background
In the prior art, the whole vehicle entering scheme of the electric vehicle mainly adopts the following two modes:
1. unlocking a vehicle door by using a remote controller, rotating an ignition switch by using a mechanical key after entering the vehicle, and starting the vehicle;
2. the intelligent key enters the system, unlocks the vehicle door through the remote control key, and directly presses the start button to start the vehicle after entering the vehicle.
The power supply state of the whole vehicle can be controlled no matter in an ignition switch mode or an intelligent key system mode, and the power supply of the whole vehicle can be controlled to enter an OFF state, an ACC state and an ON state. After the whole vehicle has the normal power (OFF), the ACC and the ON power, each controller can carry out power distribution according to the use condition. After the whole vehicle is locked, the controller needs to be designed to have a network sleep function in order to prevent the controller from consuming power all the time when the controller does not work, namely, after the whole vehicle is locked, the controller needs to enter a sleep state when the controller does not work so as to reduce power consumption, and the controller only has dark current.
The controller for the whole vehicle with normal power still has small dark current after the controller is in network dormancy, and the magnitude of the dark current is related to the length of standing time of the whole vehicle in the actual use process. If the quiescent current of the whole vehicle is designed to be too large, the number of standing days after the whole vehicle is locked is correspondingly reduced. After the vehicle is left for a period of time, the user goes to drive again and finds that the vehicle cannot be started, which is easy to cause complaints of the user.
In addition, the intelligent key system mainly comprises a remote control key, a receiving antenna on a vehicle door, an antenna in the vehicle, a starting button (comprising an anti-theft coil), a steering shaft lock, an intelligent key controller and the like. The opening and closing of the vehicle door are realized through the whole set of system, and the vehicle is started through the starting button after entering the vehicle. In the process, the identity authentication of the remote control key is ensured, and the remote control key of the user can only open the vehicle of the user and start the vehicle of the user. However, the above-mentioned keyless entry and exit scheme for the vehicle has relatively complex functions, requires many samples, and has requirements for the appearance of the vehicle, and the general requirements are that five normal doors are provided, so that a keyless detection antenna can be arranged, and there are problems that the development cost is high and rapid development cannot be performed for a specific vehicle type.

Detailed Description
The present invention is described in further detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
As shown in fig. 1, the control system for the whole vehicle entering and exiting of the electric vehicle comprises a whole vehicle controller, a whole vehicle domain controller, a corresponding control power supply and a vehicle exterior power-on switch 1 arranged outside the vehicle, wherein the vehicle exterior power-on switch 1 is connected in series to the control power supply main loop. When the vehicle exterior electrifying switch is operated to be closed, the control power supply is switched on to electrify the whole vehicle controller and the whole vehicle domain controller; when the power-on switch outside the vehicle is switched off, the control power supply is switched off to power down the vehicle controller and the vehicle domain controller.
That is, the working states of the vehicle controller and the vehicle domain controller are controlled by arranging the vehicle exterior power-on switch 1, so that the power-on and power-off of the vehicle are realized, the detection antenna arranged on the door of the vehicle, the detection antenna arranged in the vehicle, the starting button, the steering shaft lock, the intelligent key system controller and the like in the prior art can be reduced, the development cost can be reduced, and the vehicle domain controller is suitable for the rapid development of various vehicle types.
Specifically, the control system for the whole electric vehicle to enter and exit further comprises an ON electric relay 2, a READY relay 3, a positive high-voltage contactor 4, a steering control unit, a braking control unit, a motor unit, a power battery unit and a vehicle door driving motor unit. When the power-on switch 1 outside the vehicle is operated and closed, the vehicle controller and the vehicle domain controller can start working. And after the vehicle control unit is electrified, the contact of the ON electric relay and the contact of the READY relay CAN be controlled to be respectively attracted, power is supplied to the steering control unit, the motor unit and the power battery unit, after the motor unit and the power battery unit are electrified, the corresponding controllers are confirmed to be free of problems through self-checking, the controller CAN feed the problems back to the vehicle control unit through a CAN (controller area network) line, then the vehicle control unit controls the contact of the anode high-voltage contactor of the power battery unit to be attracted, the high voltage is supplied to the motor unit, and the vehicle achieves a READY state. When the whole vehicle controller controls the contact of the READY relay to be sucked, the whole vehicle controller wakes up the controllers of the steering control unit and the braking control unit through a hard wire so as to ensure that the braking control unit and the steering control unit can normally work after the whole vehicle is READY. After the whole vehicle domain controller works, the vehicle door can be driven and controlled to be opened or closed by the vehicle door driving motor unit according to the input signal of the vehicle door switch 5. After the driver enters the cab, the manual driving mode, the remote control driving mode and the automatic driving mode can be selected through the selection switch 6, and the vehicle controller controls the vehicle to enter the corresponding driving mode after receiving the input signal of the relevant mode.
In the control system for the whole vehicle entering and exiting of the electric vehicle, the power-on and power-off of the control power supply of the whole vehicle controller and the whole vehicle domain controller are controlled by arranging the power-on switch 1 outside the vehicle, and the whole vehicle controller further controls each function module on the vehicle after the whole vehicle controller is powered on, so that each function module on the vehicle can adopt a hard wire wake-up strategy instead of a sleep wake-up software strategy in the prior art, the whole vehicle controller or the whole vehicle domain controller wakes up each controller by a hard wire, or the whole vehicle controller controls the contact attraction of a READY relay to supply power to each controller, the development cost of the sleep wake-up software of each controller is saved, and the problem of software BUG caused by executing the sleep wake-up software is correspondingly reduced.
In addition, after the control power supplies of the whole vehicle controller and the whole vehicle domain controller are controlled to be disconnected through the vehicle external electrifying switch 1, the whole vehicle controller and the whole vehicle domain controller have no static power consumption; under the condition that the whole vehicle controller does not work when the power is cut off, the contact of the READY relay is disconnected due to the fact that the contact cannot be attracted, and the steering control unit, the motor unit and the power battery unit cannot generate static power consumption due to the fact that no electricity exists. For the brake control unit, the vehicle control unit does not work, so the brake control unit does not work under the condition that the vehicle control unit is not waken up by a hard wire, namely, the brake control unit enters a low power consumption mode. Therefore, only the brake control unit of the whole vehicle has static power consumption, and the static power consumption is obviously reduced compared with the prior art, so that the standing time of the whole vehicle can be effectively prolonged, the problem that the vehicle cannot be started after standing for a long time is solved, and complaints of users are avoided. Moreover, the external power-on switch 1 realizes the control of the entering and exiting of the whole vehicle in the most direct and simple mode, so that the problem of the arrangement position of the key antenna on the vehicle in the prior art does not need to be considered, and the rapid development speed of the vehicle is also improved.
Since the motor unit and the power battery unit are high-voltage and safety components, and safety under high voltage needs to be considered, the overall state of the power battery needs to be monitored within a period of time (for example, 3 minutes) after the whole vehicle is powered off. Therefore, in the control system for the whole vehicle entering and exiting of the electric vehicle, a capacitor is further arranged in the whole vehicle controller, and when the whole vehicle controller is electrified, the capacitor is charged. When the vehicle control unit is powered off, the capacitor is discharged to enable the vehicle control unit to maintain working for a preset time (for example, 3 minutes). And in the preset time, the vehicle controller keeps controlling the contact actuation of the READY relay, and simultaneously sends the vehicle descending electric signal to the motor unit and the power battery unit through the CAN line so as to provide a descending high-voltage request. The power battery unit and the motor unit can carry out system detection after receiving the power-off request signal, if the power battery unit and the motor unit have no high-voltage related faults under the influence, the power battery unit can send a confirmation response signal to the vehicle control unit, and the vehicle control unit disconnects the positive high-voltage contactor after receiving the confirmation response signal to enable the vehicle to be powered off. The vehicle controller keeps power supply to the power battery unit and monitors the safety of the power battery unit within the preset time of powering off the whole vehicle, so that the safety of a high-voltage system of the vehicle is guaranteed. And after the preset time is reached, the vehicle controller controls the disconnection of the contact of the READY relay so as to disconnect the power supplies of the steering control unit, the motor unit and the power battery unit. The control mode can normally power down the power battery unit, can meet the safety requirement and can prolong the service life of the power battery.
When the vehicle is required to stop after the driving task is finished, the work flow of exiting the vehicle and locking the vehicle is as follows: the driver controls the door driving motor unit to open the door by using a door switch in the vehicle, then controls the door driving motor unit to close the door by using a door on-board switch, controls the door lock to be locked by the whole domain controller, and then closes the power-on switch 1 on the outside of the vehicle by using a mechanical key. At the moment, the power supply of the vehicle controller and the vehicle domain controller is disconnected, the vehicle controller and the vehicle domain controller do not work any more, and the vehicle door motor does not work any more because the vehicle door lock is locked, so that the vehicle is in a vehicle locking state.
The invention also provides a control method for entering and exiting the whole electric automobile by applying the system, and the external power-on switch is arranged and connected in series into the main loop of the control power supply corresponding to the whole automobile controller and the whole automobile domain controller. When the off-board power-on switch is operated to be closed, the control power supply is switched on to power up the vehicle control unit (namely VCU) and the vehicle domain controller (namely BDC); when the power-on switch outside the vehicle is switched off, the control power supply is switched off to power down the vehicle controller and the vehicle domain controller.
Specifically, when the power-ON switch outside the vehicle is operated and closed, the contact of the ON electric relay and the contact of the READY relay of the vehicle are respectively attracted, and the braking control unit and the steering control unit of the vehicle are synchronously awakened through hard wires. And the vehicle controller controls the contact attraction of the positive electrode high-voltage contactor so as to enable the motor unit to be electrified at high voltage. The door driving motor unit of the vehicle drives the door to open or close according to the input signal of the door switch.
In the control method for the whole vehicle entering and exiting of the electric vehicle, the whole vehicle controller is connected with the motor unit and the power battery unit through CAN lines, and controls the contact of the positive high-voltage contactor to be attracted after the self-checking normal signals of the motor unit and the power battery unit are obtained.
In the control method for the whole electric vehicle to enter and exit, the whole vehicle controller is connected with the brake control unit and the steering control unit through CAN lines, and sends READY state indication information after obtaining the self-checking normal signals of the brake control unit and the steering control unit.
According to the control method for the whole vehicle entering and exiting of the electric vehicle, a capacitor is arranged in the whole vehicle controller, and the capacitor is charged when the whole vehicle controller is powered on;
when the vehicle control unit is powered off, the capacitor discharges to enable the vehicle control unit to maintain working for a preset time;
within the preset time, the vehicle controller keeps control over contact actuation of the READY relay and sends power-off request signals to the power battery unit and the motor unit;
and the vehicle control unit controls the contact of the positive high-voltage contactor to be disconnected according to the confirmation response signal of the power battery unit, so that the vehicle is charged with high voltage.
As shown in fig. 2, it is a schematic diagram of a control flow of entering and exiting of the whole electric vehicle according to the present invention. When the driver turns on and closes the external power-on switch through the mechanical key, the control power supply of the vehicle controller (namely VCU) and the vehicle domain controller (namely BDC) is turned on to be powered on.
The whole vehicle domain controller further judges whether a door opening and closing signal for opening the door is received or not, and if the door opening and closing signal for opening the door is not received, the door is not opened; and if a door opening and closing signal for opening the vehicle door is received, the vehicle door is opened. Meanwhile, after the whole vehicle controller is powered on, the whole vehicle controller wakes up the steering control unit and the braking control unit through a hard wire, and controls the READY relay to be attracted at the same time to supply power to the steering control unit, the motor unit and the power battery unit. At the moment, the vehicle control unit controls the instrument to light the READY lamp to prompt a driver that the vehicle enters a normal driving state. The whole vehicle controller, the steering control unit, the braking control unit, the motor unit and the power battery unit are also connected by CAN lines, when one controller has a fault, the whole vehicle controller CAN control the vehicle not to run, and meanwhile, the vehicle controller CAN prompt the vehicle through a related fault indicator lamp on an instrument, so that the safety of the whole vehicle CAN be ensured.
When a driver enters the vehicle, a manual driving mode, an automatic driving mode and a remote control driving mode switch in the vehicle can be selected, and the vehicle controller collects switch signals of the three mode switches and controls the whole vehicle to enter the manual driving mode, the automatic driving mode and the remote control driving mode respectively.
When the manual driving mode is adopted, a manual driving operating rod is arranged in the vehicle, and the vehicle can be controlled to move forwards, move backwards and turn through the operating rod.
When the automatic driving mode is adopted, an automatic driving controller is arranged in the vehicle, the automatic driving controller detects the surrounding environment according to sensors such as laser radar, a camera and millimeter wave radar arranged on the vehicle, and the like, and the automatic driving of the whole vehicle is carried out in a specific area (the situation that a closed place is required, and a high-precision map is provided).
When the remote control driving mode is adopted, the remote controller can be used for controlling working conditions such as vehicle running, steering and the like outside the vehicle.
When the running task is finished and the vehicle needs to be stopped, the working process of quitting the vehicle and locking the vehicle is as follows: the driver opens the vehicle door by using the vehicle door switch in the vehicle, then closes the vehicle door by using the vehicle door switch on the vehicle door, the vehicle domain controller controls the lock of the vehicle door to be locked, and then closes the power-on switch outside the vehicle by using the mechanical key. At the moment, the power supply of the whole vehicle controller and the whole vehicle domain controller is disconnected, the whole vehicle controller and the whole vehicle domain controller do not work, the vehicle door lock is locked, the vehicle door motor does not work, and the whole vehicle is in a vehicle locking and power off state.
