Abstract: PURPOSE: To improve the diagnostic accuracy of sensor abnormality by obtaining the output change rate of a sensor for detecting an air-fuel ratio or oxygen concentration in exhaust gas after detecting the change of fuel supply quantity, and judging whether the sensor is abnormal on the basis of the change rate. CONSTITUTION: An ECU 36 diagnoses whether an air-fuel ratio sensor 28 is abnormal and lights an alarm lamp 39 to inform an operator at the abnormal time, but at the time of diagnosing the abnormality of the air-fuel ratio sensor 28, starts diagnostic processing by the start of fuel cut-off and reads and stores sensor output I1 at the start time of fuel cut-off. The ECU 36 also actuates a timer to count the elapsed time after the start of fuel cut-off and reads the time until the sensor output rises to I2 from the count value of the timer so as to compute the change rate δI of sensor output. The ECU 36 then compares this change rate δI with the abnormality judgment value Ifc and judges sensor abnormality in the case of δI<Ifc. This sensor abnormality is stored in a memory.

Title: Vehicle behavior control device
Inventor: OBAYASHI SHINGO
IPC: B60W30/02
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To accurately carry out a behavior control of vehicle capable of carrying out a correction of an accurate target yaw rate corresponding to a cant of road surface without particularly adding a sensor, etc. SOLUTION: A target yaw rate correction part 15 judges whether or not a vehicle travels on an inclined road surface laterally inclined and if it travels on the inclined road surface, a lateral acceleration actually caused is accurately presumed based on the lateral acceleration detected and a roll characteristic of vehicle previously determined except for an error component caused by the roll motion. A yaw rate is operated based on a lateral acceleration expected to be small by an influence of a cant of the road surface based on these lateral accelerations. An influence against the target yaw rate caused by the cant of the road surface is presumed from the yaw rate based on the lateral acceleration and an actual yaw rate detected as a target yaw rate correction amount.  The target yaw rate from a target yaw rate calculation part 14 is corrected using the target yaw rate correction amount.
