BRAKE LIGHT LIGHTING CONTROL DEVICE IN VEHICLE WITH SLOPE START ASSISTING DEVICE

摘要

PURPOSE: To prevent the wrong recognition of braking action by a succeeding vehicle or the like by inhibiting the lighting of a brake light at the off time of an HSA valve from a brake operation holding state by the HSA valve. CONSTITUTION: A brake light lighting inhibiting relay 40 closed at the off time so as to enable the lighting of a brake light 38 and opened at the on time so as to inhibit the lighting of the brake light 38 is interposed between a brake light 38 and the on-off relay 39 of the brake light 38. At the time of turning HSA valves 20, 21 off from on by an HSAECU 32, a brake light lighting inhibiting relay control device 32a openes the brake light lighting inhibiting relay 40 only for the fixed time. Accordingly, even if pressure switches 35, 36 detect the air pressure of discharged compressed air and close the on-off relay 39, the brake light 35 is not lighted so as to prevent the wrong recognition of braking action by a succeeding vehicle or the like.
