The invention discloses a power assisting system and a braking method, and belongs to the field of vehicle braking systems. The system comprises a brake triggering device and a brake system, the brake system comprises a pressure source and a power assisting device arranged between the brake triggering device and the pressure source, the power assisting device is used for driving the pressure source to convey oil to a wheel cylinder, the brake triggering device is electrically connected with the power assisting device, a failure compensation unit is connected between the brake triggering device and the brake system, and the failure compensation unit is used for providing hydraulic braking force for the braking system when the power assisting device fails. When the power assisting device fails, hydraulic braking force is provided for the braking system through the failure compensation unit, and the problem that when a braking trigger device directly drives a pressure source of the braking system for braking through mechanical backup, a driver needs to directly drive the pressure source with the foot for mechanical driving, needed physical strength is too large and the comfort degree is low during braking can be solved.
本发明公开了一种助力系统及制动方法,属于车辆制动系统领域。该系统包括:制动触发装置、制动系统,制动系统包括压力源,设于制动触发装置与压力源之间的助力装置,助力装置用于驱动压力源向轮缸输送油液,制动触发装置与助力装置电连接,连接于制动触发装置和制动系统之间的失效补偿单元,失效补偿单元用于助力装置失效时向制动系统提供液压制动力。本申请在助力装置失效时通过失效补偿单元向制动系统提供液压制动力,能够解决通过机械备份使制动触发装置直接驱动制动系统的压力源进行制动时机械驱动需要驾驶员直接用脚驱动压力源,所需体力过大和制动时舒适度低的问题。
