Problems solved by technology

[0008] However, in the disclosed solution, the pressure difference between the pressure in the brake master cylinder and the wheel pressure is used to control and obtain the brake pedal feeling, and the designed inlet valve, outlet valve and pressure detection are still a relatively complicated method. The hydraulic control method, its efficiency and reliability need to be confirmed

Abstract

The invention provides a brake system for a vehicle. The brake system comprises a hydraulic brake unit having a brake main cylinder and configured to decelerate the vehicle through hydraulic braking, and further comprises a brake pedal, a pedal movement sensor, a control unit and a brake feeling feedback generation unit, wherein the pedal movement sensor is used for obtaining movement state information of the brake pedal in stepping; the brake feeling feedback generation unit comprises a linear electromagnetic driver set as a vehicle brake feedback feeling generation mechanism, and generates resistance of blocking the advancement of the brake pedal in response to the operation of a driver to the brake pedal of the vehicle; the resistance is applied to the brake pedal in a direct or indirect transmission manner; and the control unit is used for generating a driving signal of the linear electromagnetic driver based on the movement state information of the brake pedal. The brake system, provided by the invention, can realize the pedal brake feeling feedback in an advantageous mode when brake demands are generated.

Description

technical field [0001] Aspects of the present invention relate to regenerative braking systems for use in vehicles, particularly pure electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles, and more particularly to braking systems for vehicles and vehicles having such systems . Background technique [0002] Unlike a conventional internal combustion engine, an electric vehicle (EV), such as a pure electric vehicle, a hybrid electric vehicle, and a plug-in hybrid electric vehicle, is a battery (or capacitor, hydrogen fuel cell, etc.) Electric energy is used as the driving force of the vehicle and at least the electric motor is used as the driving force of the vehicle. It uses alternative power as the power source of the vehicle to reduce the pollution caused by vehicle exhaust, and also to make a contribution to the shortage of limited oil resources and / or natural gas resources. Prepare. [0003] It is now being studied to convert part of the braki...
