An adaptive control adjusts thresholds in a vehicle stability control in response to video camera data, GPS data and weather data indicating that vehicle road conditions are not ideal. Video data determines mue (coefficient of friction) and type of road. Weather data includes temperature, visibility, precipitation and wind velocity. A human machine interface manually overrides the adaptive control in response to a user input.

Adaptive electronic stability control

A controller for determining whether a previously-determined vehicle steering sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one vehicle sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one sensor.

Good checking for vehicle steering angle sensor

A mechanism for determining whether a malfunctioning pressure sensor has returned to a normal or acceptable operating range. The mechanism includes controllers and methods that perform a 'good check' on the sensor to determine whether the sensor has returned to normal or acceptable operation after a malfunction has been detected. When a previously-malfunctioning sensor passes the 'good check,' warning lights (or tell-tale) indicators are shut off and systems that relied upon information from the malfunctioning sensor return to normal operation.

Good checking for vehicle pressure sensor

A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a longitudinal acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller.

Good checking for vehicle longitudinal acceleration sensor

A controller for determining whether a previously-detected vehicle malfunction still exists. If the malfunction is no longer detected in the sensor signals, a vehicle control system operates in a first operational state or normal operational state with respect to the previously-malfunctioning sensor (e.g., signals from the sensor are used to control the vehicle). If the malfunction continues to be detected, the vehicle control system operates in a second operational state or malfunction state with respect to the malfunctioning sensor in which the signals from the sensor are not used to control the vehicle.

Good checking for vehicle yaw rate sensor

A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.

Good checking for vehicle wheel speed sensors

A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a lateral acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller.

Good checking for vehicle lateral acceleration sensor

A mechanism for determining whether a malfunctioning sensor has returned to a normal or acceptable operating range. The mechanism includes controllers and methods that perform a 'good check' on the sensor to determine whether the sensor has returned to normal or acceptable operation after a malfunction has been detected. When a previously-malfunctioning sensor passes the 'good check,' warning lights (or tell-tale) indicators are shut off and systems that relied upon information from the malfunctioning sensor return to normal operation.
