AI Technical Summary

Technical Problem

Existing hydraulic redundant braking solutions are slow in building up hydraulic pressure, making it difficult for drivers to quickly decelerate or stop the vehicle.

Method used

Hydraulic pressure is jointly established by two brake assemblies, and the first brake assembly and the second brake assembly are controlled to output hydraulic pressure respectively so that the sum of the hydraulic pressure reaches the target hydraulic pressure. Closed-loop control and piston pump motion control methods are used to achieve rapid establishment of hydraulic pressure.

Benefits of technology

The speed at which hydraulic pressure builds up is accelerated, enabling the vehicle to slow down or stop more quickly when the driver steps on the brake pedal, satisfying the driver's intention.

Abstract

This application relates to a hydraulic pressure building method and related products. The hydraulic pressure building method is applied to a hydraulic brake system comprising a first brake assembly and a second brake assembly. The hydraulic pressure building method comprises: determining a target hydraulic pressure required by the hydraulic brake system; controlling the hydraulic pressure output by the first brake assembly and controlling the hydraulic pressure output by the second brake assembly so that the sum of the hydraulic pressures output by the first and second brake assemblies reaches the target hydraulic pressure. This method enables faster hydraulic pressure building.
