Problems solved by technology
[0003] At present, when activating the off-road steering mode of a multi-axle vehicle, it is usually implemented by adding a physical button switch in the cockpit. Although this method is simple, it increases the hardware cost of the electronic parking brake system and the layout of the vehicle wiring harness. complexity, and it is prone to function failure or non-activation due to the failure of the physical key switch

The invention discloses a parking braking control method, a parking braking controller and an electronic parking braking system, and the method comprises the steps: determining a target working state of a vehicle based on an obtained current working state of the vehicle and a whole vehicle signal, and determining a corresponding parking braking strategy according to the target working state of the vehicle, wherein the current working state of the vehicle and the target working state of the vehicle are any one of a vehicle off-road steering mode non-activated state, a vehicle off-road steering mode pre-activated state and a vehicle off-road steering mode activated state. The vehicle off-road steering mode is activated by using the whole vehicle signal instead of an entity key switch, and the action recognition of actively activating the vehicle off-road steering mode by the driver can be realized according to any one or more of the steering wheel angle signal, the gear signal, the accelerator pedal signal and the vehicle speed signal so that the hardware cost is saved, complexity of wiring harness arrangement of the whole vehicle is reduced, and the situation of function failure or inactivation caused by faults of the entity key switch is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, and more specifically, to a parking brake control method, a parking brake controller and an electronic parking brake system. Background technique [0002] With the popularity of the electronic parking brake system, the electronic parking brake system (Electrical Park Brake, EPB for short) of ordinary two-axle vehicles has gradually replaced the traditional mechanical hand brake parking brake system. The existing electronic parking brake system of a common two-axle automobile usually adopts a single EPB control switch and a single controller (Electronic Control Unit, ECU for short) to perform parking brake on the two wheels of the rear axle. However, for multi-axle vehicles (three-axle and above), most of them still use mechanical hand brakes to carry out parking brakes at present, and compared with ordinary two-axle cars, multi-axle cars (such as three-axle military off-road vehicl...
