Driving assistance systems and methods
Systems and methods for promoting safety during operation of a passenger vehicle. Such a system/method may determine positions of rear and sideview mirrors of a passenger vehicle that are optimized for a particular driver of the passenger vehicle to minimize “blind spots” based on the driver and the particular vehicle configuration, and for moving the rear and sideview mirrors into the optimized positions. Alternatively or in addition, such a system/method may collect data corresponding to internal and external conditions of the vehicle, optionally establish a driver profile of typical driving characteristics from the collected data, determine potential risks and/or hazards from the collected data, and warn the driver of the potential risks and/or hazards.
1. A system for improving safety during operation of a passenger vehicle having rear and sideview mirrors and a passenger compartment configured to be occupied by drivers of the vehicle, the system comprising:
means for invoking a mirror optimizing capture mode while the rear and sideview mirrors are in current mirror settings, the invoking means being accessible by each driver of the vehicle when seated in a driver seat of the vehicle;
a camera subsystem used by the mirror optimizing capture mode to identify positions of the head, eyes, and nostrils of each driver when seated in the driver seat;
a subsystem of algorithms that computes driver “blind spots” of each driver when seated in the driver seat and determines optimum settings for the rear and sideview mirrors to reduce the driver “blind spots” of the driver seated in the driver seat; and
means for automatically setting the rear and sideview mirrors in the optimum settings thereof;
the subsystem of algorithms computing the driver “blind spots” based on the current mirror settings of the rear and sideview mirrors relative to the driver seated in the driver seat, internal factors comprising the height and body structure of the driver seated in the driver seat and the physical configuration of the passenger compartment of the vehicle, and external factors comprising the physical configuration of the vehicle including pillars of the vehicle.
2. The system according to claim 1 , wherein the system further comprises a camera subsystem that collects data corresponding to images displayed on rear and sideview mirrors of the vehicle and a second subsystem of algorithms to collect data corresponding to the orientations of the rear and sideview mirrors to the driver.
3. The system according to claim 1 , the system further comprising:
means for incrementally moving the rear and sideview mirrors away from the current mirror settings and moving the rear and sideview mirrors closer to the optimum settings thereof each time the driver invokes the mirror optimizing capture mode.
4. The system according to claim 3 , wherein the system allows the driver to manually alter the rear and sideview mirrors to manually-adjusted positions that are different from the optimum settings thereof.
5. The system according to claim 4 , wherein the system comprises means for visually informing the driver of the optimum settings of the rear and sideview mirrors, the manually-adjusted positions if any, and any blind spots resulting therefrom.
6. The system according to claim 3 , wherein the system comprises means to save a driver seat position of the driver seat and the optimum settings of the rear and sideview mirrors for the driver.
