Abstract

The invention discloses an electronic parking braking system evaluating method. The method comprises the steps of evaluating an EPB switching function, evaluating an automatic function, evaluating a starting release function, evaluating a dynamic parking function, evaluating a re-clamping function and evaluating a servo function. According to the electronic parking braking system evaluating method, the electronic parking braking system can be more comprehensively evaluated, the scientific and effective evaluation method is provided for the EPB performance, the various evaluation steps are feasible and effective, the problem whether the EPB control logic is reasonable or not can be comprehensively evaluated, and the vehicle safety is ensured.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an evaluation method for an electronic parking brake system. Background technique [0002] With the rapid development of the economy and the automobile industry, people's living standards have been rapidly improved, and automobiles have gradually become the means of travel for ordinary families. [0003] The use of electronic mechanical control in modern automobiles has become more and more extensive. With the innovation of automobile technology, more and more new automobile products have been upgraded from the original mechanical hand brake to the electronic parking brake system (Electrical Park Brake) , referred to as EPB). [0004] EPB uses the built-in longitudinal acceleration sensor in its computer to measure the slope, so that it can calculate the sliding force of the vehicle on the slope due to gravity. The computer applies braking force to the rear wheels through th...
