Problems solved by technology

[0004] However, when the vehicle is started with a large accelerator, the electronic parking brake system releases the rear wheels slowly, so it can produce a more obvious drag feeling. Brake the rear wheels, so after the brake is released, the front wheels provide power to pull forward, and the rear wheels are not fully released due to the relatively long response time of the electronic parking brake system, so the vehicle will produce pitch changes, which will affect the driving experience. Finally, the electronic parking brake system has a loud noise when releasing the wheels

Abstract

The invention discloses an electronic-parking-brake system with the automatic parking function, a starting method and a vehicle. According to the electronic-parking-brake system, during starting, a vehicle is converted from a brake state acted by the electronic-parking-brake system into a brake state acted by the automatic parking function, the vehicle begins to be started from the brake state acted by the automatic parking function, the vehicle can be started stably, starting noise of the vehicle is lowered, and the driving experience is improved.

Description

technical field [0001] The invention relates to the field of vehicle control systems, in particular to an electronic parking brake system compatible with automatic parking functions, a method for starting a vehicle based on the electronic parking brake system, and a vehicle using the method for starting. Background technique [0002] At present, in the motor vehicle braking system, most of the applied parking brake systems are traditional mechanical parking brake systems, and most of the traditional mechanical parking brake systems When in use, the driver needs to manually control the pull rod to perform operations such as braking when parking or releasing when starting. However, the traditional mechanical parking brake system often brings a lot of inconvenience to the driver. For example, when starting, the driver not only needs to control the steering, but also controls the accelerator and clutch, and at the same time releases the parking lever. If the parking lever is re...
