AI Technical Summary

Technical Problem

The performance of the existing hydraulic braking system declines after long-term use, weakens the braking effect, resulting in an increase in the risk of vehicle braking failure and affects driving safety.

Method used

A braking system including a first brake and a second brake is designed. The second brake has an independent parking brake cavity. The intake and exhaust state switching of the parking brake cavity is realized through the electronic control unit and the control element. It provides driving braking force in conjunction with the first subsystem to ensure that the vehicle can obtain sufficient braking force during emergency braking.

Benefits of technology

Through the dynamic control of the parking brake cavity, additional braking force can be provided through the parking brake cavity when the driving braking force is insufficient, the vehicle's braking effect and driving safety can be improved, and the service life of the brake system can be extended.

Abstract

The invention relates to a braking system, a braking control method and a vehicle. The braking system comprises a first brake, a second brake, an energy supply source, a first subsystem and a second subsystem. The first brake is arranged on a front wheel of the vehicle, the second brake is arranged on a rear wheel of the vehicle, and the power supply comprises a first output port and a second output port. The first subsystem is connected between the first output port and the service braking cavities of the first brake and the second brake and provides service braking force for the front wheels and the rear wheels. The second subsystem comprises a control part and an electric control unit, and when the electric control unit meets the preset condition, the electric control unit controls and drives the control part so that the second brake can be switched from the parking braking state to the parking braking releasing state. Traveling braking is compensated through parking braking, sufficient braking force is provided for the vehicle, and the braking effect is improved.
