The method is intended to prevent or discourage tampering with a vehicle's speed limiting system. The method includes the steps of determining whether the transmission is in neutral or whether the transmission is in its converter mode to prevent false ... 07/06/06 - 20060149441 - Failure detection device and method for oil temperature sensor for automatic transmission A failure detection device and method for an oil temperature sensor that detects an oil temperature of hydraulic fluid of an automatic transmission mounted in a vehicle. It is determined that a failure has occurred in the oil temperature sensor if the oil temperature, which is detected by the oil ... 05/18/06 - 20060106513 - Abnormality detecting apparatus for wheel speed sensors and automobile incorporating the same Wheel speed sensors arranged at each of driving wheels and idler wheels detect rotational speeds of corresponding wheels. ECU includes a wheel speed calculating portion calculating wheel speeds of the driving wheels and the idler wheels based on the detected rotational speeds, and an abnormality detecting portion detecting abnormality of ... 05/18/06 - 20060106512 - Method and device for monitoring an accelerator sensor A partially redundant, contactless pedal-travel sensor is used for controlling a vehicle. This pedal travel sensor generates at least two redundant signals using a contactless sensor and an electronic circuit. These signals are fed to a control and/or regulating unit, where they are subjected to a plausibility check to detect ... 05/04/06 - 20060095176 - Vehicle speed sensor failure detection apparatus and method for an electronic control system A vehicle speed sensor failure detection apparatus for an electronic control system having a vehicle speed sensor for generating a vehicle speed information signal indicating vehicle speed information includes a vehicle behavior detection portion, a brake sensor and a failure detection portion. If vehicle speed information generated from the vehicle ... 04/13/06 - 20060080011 - Occupant classification sensor calibration system A method of calibrating an occupant classification sensor (16) includes receiving a calibration signal originating from an on-board vehicle calibration device (24). A calibration task is performed that includes the initialization of an occupant classification sensor (16). A baseline is generated for the occupant classification sensor (16) in response to ... 02/02/06 - 20060025910 - Diagnosis monitoring device for yaw rate sensor A yaw rate sensor failure diagnosing device judges whether the yaw rate sensor is failure or not. In particular, when the vehicle is in the steady turn state, the failure is judged by comparing a yaw rate value from the yaw rate sensor with a yaw rate value calculated on ... 07/28/05 - 20050165522 - Brake booster vacuum sensor diagnostic A diagnostic system for a brake booster sensor includes a monitor that monitors a maximum error and a minimum error based on a brake booster sensor signal over a monitoring period. A first comparator determines one of a pass status and a fail status of the brake booster sensor based ... 06/16/05 - 20050131602 - Apparatus for correcting and diagnosing angular rate sensors installed in an automotive vehicle An offset diagnosing and correcting section obtains an offset correction value from an angular rate value obtained from detection signals produced from a plurality of angular rate sensors and a detection signal produced from an angular rate sensor when an automotive vehicle is in a stopped condition. The offset diagnosing ... 06/16/05 - 20050131601 - Failure diagnostic apparatus and method for an air-fuel ratio sensor A failure diagnostic apparatus is provided with an offset power source for offsetting a ground-side voltage of an air-fuel ratio sensor, an activation state judging unit for judging whether the air-fuel ratio sensor is active, a failure diagnosing unit for judging for a failure from an offset-added output signal of ... ### FreshPatents.com Support |
