A control system for a vehicle may include a plurality of vehicle subsystems associated with respective different dynamic vehicle control functions and a plurality of subsystem controllers associated with respective ones of the vehicle subsystems. The subsystem controllers may be configured to control actuators associated with the respective different dynamic vehicle control functions to change an operational state of components of the vehicle subsystems based on respective configuration settings. The system further includes an attribute configuration module operably coupled to the subsystem controllers. The attribute configuration module may include processing circuitry configured to save current configuration settings as a saved configuration responsive to a first actuation of a configuration mode actuator and, after an on/off cycle of the vehicle, instruct the subsystem controllers to implement the saved configuration responsive to a second actuation of the configuration mode actuator.

System and method for dynamic customizable vehicle configuration

A camera system and method of assisting a driver of vehicle for off-road mode use is provided. The camera system includes one or more cameras located on the vehicle to generate images of ground near the vehicle. The generated images are displayed to the driver when the vehicle is detected to be operating off-road and are prevented from being displayed when not off-road. A steering wheel direction indicator may also be displayed to the driver.

Vehicle camera system operable in off-road mode and method

A circuit monitors both digital and analog sensor readings by polling them from a single wire bus multiplex system. The circuit operates to sequentially address a plurality of smart sensor interfaces, each having an associated sensor, connected to the single wire bus. A voltage signal is supplied on the line that produces a current corresponding to the presence of a sensor at the polled interface and a current corresponding to a sensed digital or analog value where the sensor is of the digital or analog type, respectively. The currents on the bus are copied in a current mirror whose current output is applied to a resistor to produce a voltage, which in turn is converted into a digital number to be analyzed to determine the presence of a sensor at the addressed interface and its status. The current in the circuit is also measured to produce a voltage corresponding to circuit component variations and one corresponding to the contributions of the currents from the power supplies of the interfaces. These voltages correct the calculation of the voltage corresponding to the sensor analog value.

Continuous status monitoring of a plurality of switches and smart sensors associated with the switches, wherein each sensor is connected to a separate single point in a single wire bus is a affected by a smart sensor multiplex arrangement employing an automatic wake-up circuit. The automatic wake-up circuit allows activation of any switch of a group of high priority switches to automatically take a microcontroller out of a wait mode and causes it to go into a POWER-ON mode. In the POWER-ON mode, power routes all circuits in the entire system and then a polling of all the switches and sensor modules is performed.

A smart multiplex keypad scanner system for scanning a matrix of switches utilizes a portion of a clock pulse to read the switch status of one of the switches in a matrix of switches in a system in which a standard counter of a chosen modulo value that counts up to a value one less than the number of switches in the matrix is employed to generate addresses of switches in the matrix.
