Problems solved by technology

[0002] At present, when driving a vehicle with an AMT system to start on a slope, in order to prevent the car from slipping, the driver must pull the handbrake and cooperate with the accelerator to complete the start. The driver has certain difficulties in the operation, and it is easy to be in a hurry and difficult to operate; Moreover, if the slope is very large, it is difficult to ensure that the vehicle does not slide down only by the hand brake.

Embodiment Construction

[0009] Such as figure 1 As shown, the start switch 1 is connected to the TCU2 through a cable, and the TCU2 controls the clutch actuator 3, and at the same time communicates data with the ECU 4, and the clutch actuator 3 automatically controls the engagement and separation of the clutch 5.

[0010] Such as figure 2 As shown, when the start switch is pressed, does the TCU detect whether the start switch is pressed? When it detects that the start switch is pressed, the TCU also detects whether the current gear is 1st gear or reverse gear and the engine is started? If so, the TCU judges that the current state is a hill start. The TCU gives the ECU an engine speed and torque boost control, and sends an action command to the clutch actuator. After quickly engaging the clutch to the half-engagement point, the TCU detects whether the engine speed is higher than the set point. value? If the TCU detects that the engine speed is lower than the preset value at this time, the clutch a...

Abstract

The invention belongs to a vehicle technology, in particular to a control method suitable for preventing a starting AMT (Automatic Mechanical Transmission) vehicle from sliding on a slope. The control method is characterized by comprising the following steps of: firstly, adding a starting switch on an original vehicle and connecting the starting switch with a TCU (Transmission Control Unit); treading on a brake by a driver to stop the vehicle and then pressing down the starting switch when the vehicle starts on the slope; sending an action instruction to a clutch executer by the TCU detecting an electric signal so that the clutch executer is rapidly jointed to a certain depth; retarding the joint speed of the clutch when the joint depth reaches a half joint point of the clutch; loosening the brake by the driver when feeding the advancing trend of the vehicle so that the vehicle runs at a slow speed without sliding; sending a need for increasing the rotating speed and the torque of an engine to an ECU (Electronic Control Unit) by the TCU when the TCU judges that the current state is in slope starting. The method can effectively prevent sliding and is simple and convenient to operate and easy to grasp.

Description

technical field [0001] The invention relates to vehicle technologies, in particular to a control method suitable for anti-rolling when an AMT vehicle starts on a slope. Background technique [0002] At present, when driving a vehicle with an AMT system to start on a slope, in order to prevent the car from slipping, the driver must pull the handbrake and cooperate with the accelerator to complete the start. The driver has certain difficulties in the operation, and it is easy to be in a hurry and difficult to operate; Moreover, if the slope is very large, it is difficult to ensure that the vehicle does not slide down only by the hand brake. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a new control method suitable for anti-rolling when the AMT vehicle starts on a slope, the control method can effectively prevent the AMT vehicle from slipping when starting on a slope The car is simple and ...
