Safety interlock system with side area detection
First Claim
1. A safety interlock system for a bus having brakes and an anti-lock braking system capable of actively applying the brakes comprising:
- an object sensor mounted to a side of the bus capable of detecting the presence of an object in a danger zone proximate to the wheels on either side of the bus, wherein the danger zone is such that the object is in one of;
the forward path of the wheels, the rear path of the wheels, and immediately proximate thereto;
providing an activation signal based upon the object sensed within the danger zone;
a door sensor capable of detecting the open or closed state of a door of said bus 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 brakes via the anti-lock braking system to prevent motion of said bus 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.
