Title:
A lock circuit and a method of a vehicles accelerator
Document Type and Number:
Japanese Patent JP6226441
Kind Code:
B2
Abstract:
A vehicle throttle locking circuit and method are provided. A control unit (11) receives detection voltages (HV, LV) from a pedal sensor (1) and, when a clamping actuation signal (CV) is ON, digital clamping voltages (h, 1) are gradually reduced according to the detection voltages (HV, LV). A D/A conversion unit (21) converts the digital clamping voltages (h, 1) to analog clamping voltages (H, L). A variable voltage clamping unit (31) clamps the detection voltages (HV, LV) according to the analog clamping voltages (H, L). The gradual reduction of the digital clamping voltages (h, 1) are stopped when the detection voltages (HV, LV) are already clamped at an idle condition so that the pedal is effectively locked at the idle condition. As such, the present invention not only provides anti-theft function, but also avoids traffic accident and hazard to the safety of the driver or passers due to the vehicle's sudden loss of power.
