Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of an electric brake system according to an embodiment of the present invention. As shown in fig. 1, the electric brake system provided by the embodiment of the present invention adopts a decoupled design, and includes: an electronic control unit 110, a motor 120, a braking demand input unit 130, and a braking force generation unit 140; the braking force generation unit 140 includes: a rack 141, a master cylinder case 142, and a piston 143 and a brake fluid 144 provided in the master cylinder case 142; the braking demand input unit 130 includes a brake plate 131 and a brake plate stroke sensor 132. The input end of the electronic control unit 110 is electrically connected with the output end of the braking demand input unit 130, the output end of the electronic control unit 110 is electrically connected with the input end of the motor 120, and the output end of the motor 120 is connected with the rack 141.
Specifically, when a driver steps on the brake plate 131, the brake plate stroke sensor 132 can detect the stroke displacement of the brake plate 131 and generate a corresponding brake demand signal, the electronic control unit 110 receives the brake demand signal of the brake plate 131 and finally generates a brake output signal, the electronic control unit 110 controls the motor 120 to rotate according to the brake output signal, the motor 120 is connected with the rack 141, the rack 141 is controlled by the rotation of the motor 120 to move along the horizontal direction, the piston 143 is connected with the rack 141, and the piston 143 can also move along the horizontal direction; the brake fluid 144 is contained in the master cylinder housing 142, a first side fluid level of the brake fluid 144 contacts the piston 143, a second side fluid level of the brake fluid 144 contacts the brake fluid outlet of the master cylinder housing 142, the first side fluid level of the brake fluid 144 is opposite to the second side fluid level of the brake fluid 144, and the piston 143 pushes the brake fluid 144 to output along the direction that the first side fluid level points to the second side fluid level, so that braking force is generated.
Fig. 2 is a schematic flow chart of an electrically controlled braking method according to an embodiment of the present invention. As shown in fig. 2, the specific steps of the electronic control braking method include:
and S110, acquiring a braking demand signal.
Optionally, obtaining a braking travel signal of the braking plate; and determining a braking demand signal according to the braking travel signal of the braking plate.
For example, as shown in fig. 1, when the driver presses the brake plate 131, the brake plate stroke sensor 132 can detect the stroke displacement of the brake plate 131 and generate a brake stroke signal, and when the force of the driver pressing the brake plate 131 is larger, the stroke displacement of the brake plate 131 can be detected by the stroke sensor 132, and the corresponding brake stroke signal of the brake plate 131 is larger, the demand of the driver for the braking force is considered to be larger. The electronic control unit 110 can obtain a brake stroke signal of the brake plate 131, and can analyze a corresponding brake demand signal according to the brake stroke signal of the brake plate 131. For example: the stroke displacement of the braking plate 131 is 100mm, and the electronic control unit 110 analyzes that the stroke of the rack 141 corresponding to the stroke displacement of 100mm is 20mm, that is, the braking demand signal is the rack stroke, and the value of the braking demand signal is 20 mm. In other embodiments, the braking demand signal may also be a master cylinder pressure or an input current of the motor 120, and the embodiment of the present invention is not particularly limited thereto.
And S120, acquiring the state information of the vehicle.
Generally speaking, the state information of the vehicle includes a stationary state and a running state, and for example, the time when the electronic control unit receives the stroke displacement amount of the brake plate is T, the electronic control unit obtains the vehicle information at the time T, and determines whether the state information of the vehicle at this time is the stationary state or the running state according to the vehicle information.
S130, determining a braking output signal of the vehicle according to the braking demand signal and the state information of the vehicle.
Specifically, the electronic control unit analyzes the braking demand signal and acquires the state information of the vehicle, the braking output signal is determined by the braking demand signal and the state information of the vehicle, and even if the braking demand signal is the same, if the state information of the vehicle is different, the braking output signal may be different. For example, when the state information of the vehicle is in a static state, the braking demand signal is a rack stroke which is 20mm, and the braking force corresponding to the rack stroke of 20mm is larger, but it is not necessary to generate too large braking force at this time, the electronic control unit outputs a smaller braking output signal, and thus the braking output signal of the vehicle may be a signal smaller than the braking demand signal, thereby playing a role in limiting the braking output signal. According to the technical scheme provided by the embodiment of the invention, the state information of the vehicle plays a role in limiting the brake output signal, and the size of the brake output signal can be controlled according to the brake demand signal and the state information of the vehicle, so that the size of the brake output signal can be limited, the vehicle is prevented from generating excessive braking force, and the service life of the vehicle is further prolonged.
Optionally, fig. 3 is a schematic flow chart of another electronically controlled braking method provided in the embodiment of the present invention. As shown in fig. 3, a specific process of the electronic control braking method includes:
and S110, acquiring a braking demand signal.
And S121, acquiring the speed and the wheel speed of the vehicle.
And S122, determining the state information of the vehicle according to the vehicle speed and the wheel speed.
For example, as shown in fig. 1, the time when the electronic control unit 110 receives the braking demand signal is T, and the electronic control unit 110 obtains the vehicle speed V1 and the wheel speed V2 of the vehicle at the time T. The electronic control unit 110 determines whether the state information of the vehicle is a stationary state or a running state according to the vehicle speed V1 and the wheel speed V2. Alternatively, if vehicle speed V1 is less than or equal to threshold vehicle speed V1 'and wheel speed V2 is less than or equal to threshold wheel speed V2', then the vehicle is determined to be stationary; if vehicle speed V1 is greater than threshold vehicle speed V1 'or wheel speed V2 is greater than threshold wheel speed V2', then the vehicle is determined to be in a driving condition.
If the state information of the vehicle is the driving state, executing S133; if the state information of the vehicle is in a stationary state, S131 is executed.
S131, judging whether the braking demand signal is larger than the braking limiting signal.
If yes, go to S132; if not, go to step S133.
S132, determining the brake limiting signal as a brake output signal of the vehicle;
s133, determining the braking demand signal as a braking output signal of the vehicle.
Specifically, if the state information of the vehicle is a static state, the braking demand signal is compared with the braking limit signal, where the braking limit signal may be a rack stroke, a master cylinder pressure, an electrode input current, or the like, and is not particularly limited. If the braking demand signal is greater than the braking limit signal, the braking force corresponding to the braking demand signal is greater than the braking force corresponding to the braking limit signal, and because the state information of the vehicle is in a static state, excessive braking force is not needed, the braking limit signal is used as a braking output signal of the vehicle to generate smaller braking force; if the braking demand signal is less than or equal to the braking limit signal, the braking force corresponding to the braking demand signal is less than or equal to the braking force corresponding to the braking limit signal, and therefore the braking demand signal is used as a braking output signal of the vehicle to generate smaller braking force. In addition, if the state information of the vehicle is a driving state, the braking demand signal is a signal generated according to an actual situation, and the braking demand signal needs to be determined as a braking output signal of the vehicle so as to generate braking required according to the actual situation.
For example: if the state information of the vehicle is in a static state, the brake limiting signal is a rack stroke and the specific value is 10mm, and if the brake demand signal is the rack stroke and the specific value is 20mm, the brake output signal is 10 mm; if the braking demand signal is the rack stroke and the specific value is 8mm, the braking output signal is 8 mm.
The embodiment of the invention not only can meet the braking requirement of the vehicle in a static state, but also can reduce the maximum pressure of the master cylinder, avoid generating overlarge braking force and further prolong the service life of the vehicle. In addition, the vehicle can generate a braking force desired by the driver in a traveling state, and safety during normal driving can be maintained.
Optionally, before acquiring the braking demand signal, the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor are subjected to self-checking to determine whether the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor are effective.
For example, effective signal ports are arranged on the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor, and whether the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor are effective or not can be determined according to whether electric signals exist in the effective signal ports or not; if the vehicle is invalid, a fault alarm lamp is lightened to prompt a driver to carry out inspection and maintenance. The embodiment of the invention only exemplarily shows that whether the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor are effective is determined through the effective signal port, and in practical application, whether the brake plate stroke sensor, the vehicle speed sensor and the wheel speed sensor are effective can also be determined in other ways.
Based on the same inventive concept, the embodiment of the invention also provides an electric control braking device which can execute the electric control braking method provided by any embodiment of the invention and has corresponding functions and beneficial effects of the method.
