Embodiment Construction

[0036] In order to provide a solution for avoiding undesired closing of the clutch and causing undesired acceleration of the vehicle, the embodiment of the present invention provides a clutch control method, controller and control system. The following describes the embodiment of the present invention in conjunction with the accompanying drawings It should be understood that the embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] The applicant has found through research that, in the prior art, the clutch is used for the coupling connection between the power source and the gearbox, and controls the transmission of all or part of the torque of the power source to the gearbox. However, if the current vehicle condition does not allow the power source to outp...

Abstract

The invention discloses a clutch control method, a controller and a control system; the method comprises the steps of: judging whether the clutch is currently allowed to be closed or not according tovehicle running parameters, wherein the vehicle running parameters comprise vehicle speed, shift lever position and brake pedal position; monitoring the position deviation value of the clutch if the clutch is not currently allowed to be closed; and controlling the clutch to open according to the position deviation value when the position deviation value of the clutch is not 0. According to the above process, when the clutch of the vehicle is not allowed to be closed and the clutch has been closed, the clutch is controlled to be opened in time according to the position deviation value of the clutch, so that the clutch cannot transmit the torque output from a power source to a gearbox, so the problem of unexpected acceleration of the vehicle under the action of suddenly increased torque is avoided, and the safety of a driver when driving the vehicle is further improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a clutch control method, a controller and a control system. Background technique [0002] The clutch is located between the power source and the gearbox. When the clutch is closed, the torque output from the power source to the gearbox is transmitted, and when the clutch is opened, the torque output from the power source to the gearbox is cut off. If the current vehicle condition does not allow the power source to output torque to the gearbox, that is, the current vehicle condition expects the clutch to be turned on, if there is a position deviation of the clutch at this time, it means that the clutch will transmit the torque output from the power source to the gearbox, which will cause the vehicle to generate abnormal Acceleration is expected, and vehicle driving safety is poor. Contents of the invention [0003] The technical problem solved by the present application is to ...
