Currently, passenger cars increasingly use driver assistance systems such as Advanced Driver Assistance systems (ADAS) to minimize driver error and improve general driving behavior. ADAS may include several sub systems, for example, Hill Descent Control (HDC), Anti-lock Braking systems (ABS), Electronic Stability Program (ESP), parking assist, adaptive cruise control, lane assist, etc., employing a plurality of sensors. In general, such systems aid an operator or driver of a vehicle in avoiding collisions and improving ride comfort. However, in evaluating ride comfort, existing systems generally assess attributes corresponding to improved ride comfort from the perspective of the operator or driver alone.
Typically, in all-terrain vehicles (ATVs) with two rows of seating, rear passengers experience a different level of comfort than the operator or front passenger of the vehicle. Consequently, differing perceptions create a gap in the understanding of the severity of driving style for the operator. For instance, the driver may often cross obstacles at a speed that is comfortable for the front seat but may be unaware that the rear passengers are much less comfortable. Alternately, while passing through routes having continuously winding roads, the driver may negotiate bends or curves at excessive speed. In the case of a timid rear passenger or a child, they may not communicate to the driver to slow down or to alter his/her driving style. In such cases, the rear passenger may experience discomfort. Consequently, the rear passengers experience a reduced enjoyment of the ride. As such, a mechanism or device that detects instantaneous acceleration experienced by the rear passengers and subsequently notifies the driver of the vehicle is desired.
In recent years, large technological advances have been made in the field of driverless or autonomous vehicles. Typically, autonomous vehicles rely on a plurality of sensory inputs to achieve situational and self-awareness. Despite the obvious advantages of employing driverless vehicles, the perceived lack of control on the part of passengers have posed significant concerns. As such, a feedback system controllable by passengers that modify acceleration of autonomous vehicles based on perceived passenger discomfort is therefore desirable. Further, such a feedback system must not be prohibitively expensive to produce and implement.
Hence, there is a long felt but unresolved need for a device, which instantaneously detects acceleration experienced by the rear passengers and subsequently notifies the driver of the vehicle. Furthermore, there is a need for a feedback system controllable by passengers that modify acceleration of autonomous vehicles based on perceived passenger discomfort.
