specific Embodiment approach
[0045]As a specific implementation of the embodiment of the present invention, the wheel signal is converted into the vehicle speed, specifically:
[0046] The wheel signal is processed and filtered by the crossover algorithm, and the wheel signal after filtering the noise is converted into the vehicle speed.
[0047] In the embodiment of the present invention, the crossover algorithm is used to process and filter the wheel signal, which can effectively reduce the impact of noise in the wheel signal on data conversion, thereby effectively reducing the deviation and making the converted vehicle speed more accurate.
[0048] As a specific implementation of the embodiment of the present invention, the driving state information of the vehicle is collected, and after it is judged that the driving state information of the vehicle meets the preset conditions for starting the steep slope descent control, a control command is sent to compare the first braking distance and the second bra...

The invention discloses an electronic caliper-based steep slope descending control system, comprising: a control device, a left brake disc, a right brake disc, an electronic parking caliper assembly, a sensor assembly and a steep slope connected to the control device A slow-down switch; the control device is configured to: determine whether the current road condition of the vehicle is a steep-slope road condition according to the gradient; after judging that the current road condition of the vehicle is a steep-slope road condition, convert the wheel signal into a vehicle speed to obtain the vehicle speed The current speed of the vehicle is collected; the driving state information of the vehicle is collected, and after judging that the driving state information of the vehicle meets the preset conditions for starting the steep slope descent control, a control command is sent to adjust the first braking distance and the second braking distance. Adjust to a preset range; when it is detected that the gradient value does not exceed the preset threshold range, it is determined that the vehicle is not in a steep slope road condition, and a control instruction is sent to adjust the braking distance to a preset value. The embodiments of the present invention can effectively reduce the cost of steep slope descent control.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to an electronic caliper-based steep slope descent control system. Background technique [0002] At present, with the development of automotive electronics, more and more models are equipped with slope descent function on the market. At present, the control method of the steep slope descent system of most models is: when the control button of the steep slope descent system is pressed, the current slope is greater than the designed slope value, the accelerator pedal and the brake pedal are released, the body electronic The controller of the stability control system obtains the required braking force based on the algorithm, and then controls the pressure of the brake line so that the vehicle can drive at a constant speed, and the vehicle enters the operating state of steep slope and slow descent. [0003] However, the existing hill descent control system requires a built-in h...
