ERRONEOUS OPERATION PREVENTING DEVICE FOR SHIFT LEVER OF AT VEHICLE

摘要

PURPOSE:To previously prevent the inadvertent shift operation on start by outputting an alarm when the engine revolution is detected and the output signals of the first and second sensors are received at the same time and a brake pedal is not depressed. CONSTITUTION:An engine revolution sensor 31 detects the revolution of an engine. A brake sensor 33 detects the depression of a brake pedal. The first sensor 21 detects that a shift lever 1 is at an N-position. Further, the second sensor 11 is installed on the shift lever knob 2 of the shift lever 1, and detects the gripping of the shift lever knob 2. A computer 40 as the first alarm output means outputs an alarm from an alarm device 50 when signals are inputted from the engine revolution sensor 31 and the first and second sensors 2 and 11 at the same time and the signal of a brake sensor 33 is not inputted.
