CONSTANT-SPEED RUNNING DEVICE FOR CAR

摘要

PURPOSE:To further improve the easiness of using a constant-speed running device by automatically converting to the constant-speed running state when the running speed is kept within the designated range of fluctuation more than a designated time. CONSTITUTION:Servo driving means (f) is adapted to control a throttle valve to open or close according to a setpoint from a throttle opening control means (e) for constant-speed running when the throttle opening control means for constant-speed running is in a set condition and according to a setpoint from a throttle opening control means for acceleration following running. Set timing control means (h) is adapted to set the throttle opening control means (e) for constant-speed running under a designated condition, and set the throttle opening control means (e) for constant-speed running under the condition that detected car velocity is kept within the designated range of fluctuation extending over a specified time, and the detected accelerating operation amount is zero.
