Abstract

A vehicle stop detecting apparatus including a detecting device for detecting a parking brake inoperative condition in a vehicle, and a signal generating device for generating a vehicle stop signal when a parking brake operative condition is generated after detection of the parking brake inoperative condition by the detecting device. Accordingly, in the case where a wiring is not properly connected, causing that the parking brake lever is in a position corresponding to the parking brake inoperative condition, the generation of the vehicle stop signal can be prevented. Further, a vehicle stop condition can be reliably determined with a simple construction.

Claims

1. A vehicle stop detecting apparatus for enabling operation of other apparatus in response to a vehicle stop signal, comprising:

detecting means for detection an operative or inoperative parking brake condition in a vehicle;

signal generating means for generating a vehicle stop signal when a parking brake operative condition is detected after detection of a parking brake inoperative condition by said detecting means; and

reset means responsive to operation of a vehicle accessory switch, to cause the resetting of said signal generating means, wherein said signal generating means includes means for inhibiting said signal generating means from generating said vehicle stop signal if a parking brake operative condition is present when said signal generating means is reset.
