Outline
For the vacancy of the redundant braking system selection method, according to the performance requirements of the braking system, a design and verification method for the relevant components of the redundant braking system including motor, piston pump and solenoid valve was proposed. In this method, the deceleration index is transformed into the brake fluid pressure index through the theoretical calculation of vehicle dynamics, and the brake fluid pressure index is transformed into the liquid volume index through the pressure-volume characteristics of the braking system, and the liquid volume index is transformed into the flow index based on the response time requirement, so as to determine whether the solenoid valve scheme meets the requirements. Based on the structure and working principle of the motor and piston pump, the AMESim simulation model of the redundant braking system was established, and the simulation results were analyzed to determine whether the motor and piston pump scheme met the requirements. According to the vehicle parameters and brake parameters of a certain vehicle, the scheme check of the redundant braking system is carried out by using this method, which could provide support for the scheme selection of the redundant braking system.
