Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.

A system and method for adjusting engine settings and/or calibrations is based on engine and/or vehicle parameters, and/or environmental conditions, and is further based upon a forecasted drive cycle, forecasted driving condition, vehicle vocation, vehicle geographic location, vehicle load, type of operation, season of the year, vehicle system or subsystem condition and/or operation, and/or other factors. An engine of the vehicle has an ECU configured to store and implement an engine control map. At least one algorithm is operable to determine an engine control map specific to an engine operating parameter, a vehicle operating parameter, an environmental condition, and/or an expected range of settings and calibrations. At least one device is configured to wirelessly upload to the vehicle the specific engine control map, and then load or flash the specific engine control map to the ECU.

An auxiliary power system for a motor vehicle includes a power generator that generates electricity to charge one or more auxiliary power system batteries. The motor vehicle includes an engine and drive train that distributes power from the engine to the drive wheels. The drive train can include a transmission, a drive shaft and a differential that connects the engine to the drive wheels. The power generator can be connected to the drive train (e.g., the transmission, the drive shaft or the differential) to draw power to generate electricity as well as to apply braking loads on the drive wheels to increase the ability to stop the motor vehicle.

Various methods of detecting or controlling vehicle stability are disclosed. Certain embodiments provide a method for performing hill hold control for a vehicle, a method for detecting a vehicle sliding into loss of control, and/or a method for controlling a vehicle's sliding into loss of control. Methods for detecting sliding into loss of control may include comparing the vehicle's longitudinal velocity gradient with a reference speed computed from wheel speed sensors inputs and/or detecting a lateral velocity of the vehicle and a longitudinal velocity of the vehicle when vehicle sliding is detected. Methods for control may include calculating a vehicle pitch angle from the lateral acceleration, the longitudinal acceleration, the yaw rate, the roll rate, and the pitch rate, calculating a longitudinal velocity gradient from the vehicle pitch angle, and/or calculating a sideslip angle.

One of the most popular and exhilarating stunts in off-road vehicle driving is catching air off a jump. Unfortunately, once the vehicle is in the air, the driver loses significant control of the vehicle. An electronic vehicle control system is described herein that addresses this problem. The system may include an ABS module, a shock position sensor, and an ABS override module. The ABS override module may be coupled to the shock position sensor and the ABS module. The ABS override module may receive a shock-extended signal from the shock position sensor indicating one or more of the shocks are fully extended. The ABS override module may send a stop-ABS signal that may prevent the ABS module from operating. The ABS override module may additionally be connected to a yaw rate sensor, the brakes, and the throttle, and may automatically control the pitch, roll and yaw of the vehicle.

This gear shifting control device is equipped with a pedal operation detection unit (42) and a control unit (60). The control unit (60) includes a change rate calculation unit (60a) which calculates a time change rate (DFSA) of a pedal load detection value (FS), a load prediction unit (60b) which obtains a pedal load prediction value (FSC), a pedal load determination unit (60c) which determines whether or not the pedal load detection value (FS) reaches a first threshold value (FSCC), a predicted value determination unit (60d) which determines whether or not the pedal load prediction value (FSC) exceeds a second threshold value (FSCTC) when the pedal load detection value (FS) reaches the first threshold value (FSCC), and an output suppression control unit (60e) which performs output suppression control when it is determined that the pedal load prediction value (FSC) exceeds the second threshold value (FSCTC).

A control system for a hybrid transmission of a vehicle, the hybrid transmission having first and second electric motors, comprises a motor speed sensor configured to measure a rotational speed of the first electric motor and a controller. The controller is configured to determine a first difference between a first measured speed and a first expected speed of the first electric motor, when the first difference exceeds a speed threshold indicative of tire slippage, temporarily adjust a torque output of the second electric motor to compensate for an oscillation generated by the first electric motor, after controlling the second electric motor to temporarily adjust its torque output, determine a second difference between a second measured speed and a second expected speed of the first electric motor, and when the second difference does not exceed the speed threshold, control the second electric motor based on a driver torque request.
