Title: Up-slope start assisting device
Inventor: OONISHI YUUICHI
IPC: B60T7/12
Filed: 1994-09-27
Abstract: PURPOSE: To temporarily hold braking pressure even if a brake pedal is released when a clutch is stepped by containing a means in a control circuit so as to prohibit sending-out of control output when the acceleration information shows deceleration when horizontal directional acceleration information is taken in. CONSTITUTION: When car speed is zero, horizontal directional acceleration information α is taken in from an acceleration sensor 8, and whether or not the acceleration information(X shows deceleration (α<0) is judged. When it shows the deceleration, it is judged that true speed is not zero, and sending-out of a control signal to a solenoid valve 1 is prohibited, and sloping road departure assisting operation is stopped. When it does not show the deceleration, since the car speed is reliably zero, when a stroke of a clutch pedal 12 exceeds a prescribed value, the control signal is sent out to the solenoid valve 1, and the sloping road departure assisting operation is performed.
