Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] figure 1 It is a structural schematic diagram of the current EPB system. Such as figure 1 As shown, the current EPB system includes: an EPB controller 11 , a first brake 12 and a second brake 13 . Both the first brake 12 and the second brake 13 are connected to the EPB controller 11 . The EPB controller 11 controls whether the first brake 12 and the second brake 13 are in a released state or in a braking state. However, the reliability of the EPB system is low. For example, when the EPB controller 11 fa...

Abstract

The invention discloses a parking braking method, system and device, a vehicle and a storage medium. The method comprises the following steps: according to a current vehicle condition, determining a first brake control instruction and a second brake control instruction; and through a first loop network among a brake controller, a first area controller and a second area controller, sending the first brake control instruction to the first area controller, and sending the second brake control instruction to the second area controller so that the first area controller controls the first brake according to the first brake control instruction, and the second area controller controls the second brake according to the second brake control instruction. According to the parking braking method provided by the embodiment of the invention, requirements of laws and regulations can be met without arranging an additional parking braking device, vehicle cost is reduced, and meanwhile, high-performanceand high-reliability parking braking can be realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of automobile control, in particular to a parking brake method, system, device, vehicle and storage medium. Background technique [0002] With the development of the automobile industry, the number of automobiles is increasing. According to the mandatory regulations of the national standard GB 21670, when the internal circuit of the electronically controlled transmission and the external circuit of the electronic control unit except the power supply circuit are damaged or the control device fails, the parking brake can still be performed from the driving position and the fully loaded vehicle can be stopped at 8%. The up and down ramps remain stationary. [0003] At present, in addition to the electronic parking brake (Electrical Park Brake, EPB) system, the vehicle also needs to be equipped with other parking brake devices, such as E-Park or P lock, so as to realize the EPB in the EPB system...
