Abstract

This invention discloses one method and device to prevent automobile move back on slope, which fixes one single direction locking device on low speed gear or reverse gear to make the car main axis only rotate forward when in low speed gear with its reverse direction locked up to prevent the moving back when climbing up the slopes or sliding forward.

Description

【Technical field】 [0001] The invention relates to a method and a device for preventing a car from sliding on a slope, in particular to a method and a device for preventing a car from sliding on a slope suitable for electronically controlled mechanical automatic transmissions or manual transmissions. 【Background technique】 [0002] During the driving process of the car, due to the complex and changeable road conditions, there are often problems that are more or less easily overlooked in the design of the car, including such a situation: that is, when the vehicle is started on an uphill section, due to the separation of the clutch from disengagement to engagement, there will be problems due to When the power is interrupted, the car will slide backwards when starting on a slope. The driver usually needs to cooperate with the accelerator pedal, hand brake or foot brake to avoid sliding. Like this, for on the steep slope of mountain road, there is certain potential safety hazard ...
