SAFETY INTERLOCK SYSTEM WITH SIDE AREA DETECTION
First Claim
1. A safety interlock system for a motor vehicle having vehicle brakes and an anti-lock braking system capable of actively applying the vehicle brakes comprising:
- an object sensor mounted to a side of the vehicle capable of detecting the presence of an object in a danger zone near said motor vehicle and providing an activation signal;
a door sensor capable of detecting the open or closed state of a door of said motor vehicle and providing an open door signal upon opening of said door and a close door signal upon closing said door; and
a control circuit activating said safety interlock system after said open door signal is received and deactivating the interlock system after said close door signal is received, whereupon said control circuit activates said vehicle brakes via the anti-lock braking system to prevent motion of said vehicle when said activation signal is received from said object sensor and said safety interlock system is activated.

Abstract
A safety interlock system for a motor vehicle has a plurality of object sensors capable of detecting the presence of an object such as a pedestrian in the danger zone at the front of the vehicle, rear the vehicle or proximate to the wheels. A door sensor is capable of detecting the open or closed state of the vehicle doors. An interlock override switch and a control circuit are also connected to the safety interlock system. The control circuit is capable of activating the safety interlock system when a door open signal is received. When the safety interlock system is activated the control circuit may engage the brakes to prevent motion of the vehicle if an object signal is received from the object sensor.

12. A safety interlock system for a motor vehicle having vehicle brakes and an anti-lock braking system capable of actively applying the vehicle brakes comprising:
-
an object sensor capable of detecting the presence of an object in a danger zone on a side of said motor vehicle proximate to a vehicle wheel and providing a detection signal; a door sensor capable of detecting the open or closed state of a door of said motor vehicle and providing an open door signal after opening of the door and a close door signal after closing the door; a control circuit activating said safety interlock system when said open door signal is received and deactivating the interlock system when said close door signal is received, the control circuit activating said vehicle brakes to prevent motion of the vehicle when said detection signal is received from said object sensor and said safety interlock system is activated; and an interlock override switch allowing an operator of said motor vehicle to temporarily deactivate said safety interlock system during one cycle of activation by the open door signal. - View Dependent Claims (13, 14)
