DISPLAY OF ROAD ANGLE CHANGING AND SAFETY DEVICE ON THE UPHILL ROAD DRIVING

摘要

The present invention relates to a driving safety device for a vehicle. The present invention is to notify a driver of a sudden change of a road inclination angle when driving uphill and to shift down the gear stage of an automatic transmission for safe driving. The present invention connects the inclination angle sensor for determining the uphill, the vehicle speed sensor for calculating the vehicle speed, and the output of the ultrasonic transmission / reception sensor for detecting the road surface condition in front of the vehicle to the input of the automatic transmission control device, When it detects that the ultrasonic reflection distance is more than the predetermined distance while the vehicle speed exceeds the certain speed and operates the buzzer connected to the output of the control device, the engine brake is activated by sending a shift-down control signal to the transmission hydraulic control device. It is characterized in that.
