Roll Lock Mechanism for Parking Vehicles on an Inclined Surface

Disclosed is a Roll Lock Mechanism (RLM) for parking vehicles on an inclined surface. The RLM is a micro-controller enabled locking mechanism. The RLM enables prevention of backward or forward rolling of wheels of a vehicle which is parked on an inclined surface. A block diagram illustrating the RLM is shown in fig. 1

Figure 1

A driver is required to switch on the RLM of the vehicle to an enable mode while parking the vehicle in the inclined surface. A switch for the RLM may be provided in the dash board of the vehicle for this purpose. In the switch on mode, the RLM can detect any changes in gear of the vehicle. The RLM utilizes a Gear Shift Detection System (GSDS) which is attached to Gear Box of the vehicle for detection of changes in the gear. In case gear of the vehicle is changed to forward/rear gear by the driver, the GSDS sends a signal to a RLM controller unit. The RLM controller unit is a micro-controller included electronic circuit system. The RLM controller unit reads the signal and passes instruction to an Axle Locking System (ALS) which is attached to axle of the vehicle. The ALS locks wheel from rolling in backward/forward direction based on the gear changed.

Further, as the vehicle is in off position and the gear is shifted to Neutral, the GSDS senses this shift and sends a signal to the RLM controller unit. The RLM controller...
