Output control device for vehicle

摘要

An output control device configured to control the output of a running drive source mounted on a vehicle includes an anomaly discriminator which judges that the output control device is anomalous, if excess acceleration G (output difference index) of the vehicle remains greater than or equal to a predetermined threshold value G1, . . . , G7 for a predetermined time t1, . . . , t7 or longer, wherein the predetermined time t1, . . . , t7 for the anomaly discrimination is set so as to shorten with increase in the threshold value G1, . . . , G7 of the excess acceleration of the vehicle.

1. An output control device configured to control output torque of a running drive source mounted on a vehicle, comprising:
a plurality of measuring units which measure, for a plurality of predetermined threshold values, amounts of time for which an output difference index remains greater than or equal to the respective threshold values; an electronic control unit that controls the drive source; and a storage medium, having stored there on instructions which when read by the electronic control unit cause the electronic control unit to perform the steps of calculating, based on operation of an accelerator of the vehicle, an allowable torque that the running drive source is allowed to generate in response to a driver's request; calculating, based on an operating condition of the vehicle, an estimated torque that is estimated to be actually output by the running drive source; calculating an output difference index correlated with a difference between the allowable torque and the estimated torque; and determining whether or not the amounts of time measured by the plurality of measuring units are greater than or equal to respective discrimination times predetermined for the respective threshold values and judging that the output control device is anomalous if at least one of the amounts of time measured by the measuring units is determined to be greater than or equal to its associated discrimination time wherein the discrimination times are predetermined such that discrimination times for greater threshold values are shorter.
