Problems solved by technology

[0009] The technical problem to be solved by the technical solution provided by the present invention is that the electronic parking brake system cannot confirm whether the power has been transmitted to the wheels in a motor vehicle without a gear sensor and a clutch sensor, and the installation of a clutch position sensor and a gear The increased cost of the sensor, the large error of the clutch position sensor lead to technical problems such as misjudgment of the electronic parking brake system, and the greatly reduced life of the clutch. An electronic parking brake system and its auxiliary starting method applied to motor vehicles are provided.

Embodiment Construction

[0059] In the electronic parking brake system, the conditions for realizing automatic parking are relatively easy to judge. When the vehicle speed is zero, the vehicle can be parked without any problems. However, it is difficult to judge the conditions for automatic release, because possible safety hazards should be considered when releasing, and the slope cannot be caused by premature release, nor can the engine be turned off or even damage the transmission system because the automatic release is too late. To judge whether it can be released automatically, it is necessary to know whether power has been transmitted to the wheels and whether this power is enough to ensure that the vehicle does not slide.

[0060] At present, on a motor vehicle without a gear sensor and a clutch sensor, the clutch position and gear information cannot be obtained. To determine whether the power is transmitted to the wheels, it is necessary to install a clutch position sensor and a gear sensor to ...

Abstract

The invention discloses an electronic parking brake system for a motor vehicle and an auxiliary starting method thereof. The electronic parking brake system comprises an electronic parking brake controller and an actuation mechanism, one end of the electronic parking brake controller is connected with the actuation mechanism, while the other end thereof is connected with a vehicle body CAN bus; an engine controller, an electronic stabilization plant (ESP) controller and a vehicle body controller are connected with the electronic parking brake controller through the vehicle body CAN bus. With the technical scheme provided by the invention, the technical problems of cost increase, the misjudgment of the electronic parking brake system due to big error of a clutch position sensor, great reduction in the service life a clutch and the like can be effectively solved; meanwhile, the electronic parking brake system has the advantages of avoiding periodical clutch calibration, starting without operating a parking brake pull rod, along with low cost and good adaptability.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle brake system manufacture, and in particular relates to an electronic parking brake system applied to a motor vehicle and an auxiliary starting method thereof. Background technique [0002] At present, in the field of motor vehicle brake system manufacturing technology, most of the applied parking brake systems are traditional mechanical parking brake systems. The traditional mechanical parking brake system mostly consists of a parking brake pull rod, a cable, and a brake. The driver manually manipulates the parking brake lever to complete the parking brake or release. The traditional mechanical parking brake system often brings a lot of inconvenience to the driver. Specifically, when starting off, the driver not only needs to control the steering, but also controls the accelerator and clutch, and simultaneously releases the parking brake lever. This makes getting started very complicated....
