Problems solved by technology
In the creeping process, some special working conditions are usually encountered. For example, when creeping up a slope, when the gradient load exceeds the resistance that the vehicle can overcome by creeping, the vehicle will stop on the slope and cannot move forward or backward. If this If creep protection is not adopted, the temperature of the clutch will be too high, resulting in ablation of the clutch and damage to the hardware of the vehicle.

Embodiment Construction
[0011] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0012] The invention discloses a vehicle creep protection method, see figure 1 , its basis is divided into four steps, and each step will be described below.
[0013] Step 1 is: judging whether the state of the vehicle is creeping state, if so, proceed to step 2. If the judgment of this step is no, it proves that the vehicle is not in a creeping state, and creep protection is not required. Of course, there may be a failure as a whole, and the creeping action is not performed. This problem will be explained below the manual.

The invention discloses a vehicle creep protection method, which comprises the following steps: step 1: judging whether a vehicle state is a creep state or not; if so, entering into step 2; step 2: judging whether that vehicle reach the maximum load, otherwise returning to the step 1, if yes, entering the step 3; step 3: judging whether there is external interference, withdraw from that creeping state if there is external interference, reducing the power output of the vehicle creep if there is no external interference, and simultaneously entering the step 4; step4: judging whether that power output in the step 3 is reduced to 0, and judging whether the time for reduce the power output is longer than a predetermined time, if either of the two is yes, disengaging the vehicle power system; wherein the external intervention comprises any one of stepping on the accelerator, increasing the power, and the external application of power to the vehicle. The vehicle creeping protection method ofthe invention can protect the vehicle from creeping under special working conditions and avoid the clutch from ablating due to excessive high clutch temperature and causing damage to the vehicle hardware.
Description
technical field [0001] The invention relates to a vehicle creep protection method. Background technique [0002] The vehicle creep function refers to the function of the vehicle running at a certain speed when the driver releases the brake and does not step on the accelerator. The vehicle creep function is one of the important driving functions of the vehicle, and it is also an essential part. In the creeping process, some special working conditions are usually encountered. For example, when creeping up a slope, when the gradient load exceeds the resistance that the vehicle can overcome by creeping, the vehicle will stop on the slope and cannot move forward or backward. If this When creep protection is not adopted, the temperature of the clutch will be too high, resulting in ablation of the clutch and damage to the vehicle hardware. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle creep protection method to avoid vehicle har...
