초록 ▼

Disclosed is an automatic safety driving distance control device for vehicle. The device includes a microcomputer which, within the range of 0-120 km/hr, can adjust the safety distance between the vehicle and the front vehicle according to the speed data transmitted from the speedometer and can automatically control the speed of the vehicle to maintain a safety distance from the front vehicle so as to avoid collision. When the vehicle is moving, the microcomputer calculates the safety distance between both vehicles according to the speed of the vehicle and the actual distance from the front vehicle according to the data from the distance detector. If the distance is too short, it will automatically motivate the brake motor to cause the vehicle to decelerate and the brake lights to turn on; if the distance is too great, it will automatically motivate the accelertion/deceleration motor to cause the vehicle to accelerate so that a safety distance is kept between both vehicles. If the front vehicle stops, then the brake motor and acceleration/deceleration motor will be motivated to stop the vehicle. If the front vehicle moves forward, the acceleration/deceleration motor will also be motivated, and the vehicle moves forward, keeping a safety distance from the front vehicle and maintaining a safety speed according to the value set by the speed limit device.

대표청구항 ▼

A safe driving distance control device for a vehicle comprising: microprocessor means for calculating a safe distance to be maintained between the vehicle and a second vehicle in front of the vehicle and outputting signals indicative thereof to achieve automatic acceleration/deceleration, automatic braking, automatic safe driving distance control, automatic speed limiting, automatic advance lighting of brake lights, and second vehicle speed indication; a speedometer for measuring the speed of the vehicle and providing speed signals indicative thereof to the microprocessor means; means for detecting a distance between the vehicle and the second vehicle and providing distance signals indicative thereof to the microprocessor means; means for controlling an automatic brake main pump of the vehicle in accordance with the signals provided by the microprocessor means to brake the vehicle, the automatic main brake pump controlling means being coupled to a manual brake main pump of the vehicle to enable the vehicle to be manually braked independent of the automatic main brake pump controlling means; means for controlling an acceleration/deceleration motor of the vehicle in accordance with the signals provided by the microprocessor means to accelerate/decelerate the vehicle, the acceleration/deceleration motor controlling means being coupled to a manual accelerator of the vehicle to enable the vehicle to be manually accelerated independent of the acceleration/deceleration motor controlling means; a speed setting device for setting a speed limit, the microprocessor means controlling the speed of the vehicle in accordance with said speed limit to cause the vehicle to automatically decelerate when the speed of the vehicle is greater that the speed limit and to cause the vehicle to automatically accelerate when the speed of the vehicle is less than the speed limit; means for energizing the brake lights when the microprocessor means provides the signals to one of brake and decelerate the vehicle to cause the brake lights to illuminate prior to braking of the vehicle; and a front car speed indicator for indicating the second vehicle speed, the second vehicle speed being calculated by the microprocessor means in accordance with the speed signals and distance signals provided by the speedometer and the distance detecting means.
