Onboard control device
View Patent ↗An onboard control device has a drive manipulated variable detection unit ( 101 ) for determining a drive manipulated variable manipulated by a driver to impart a propulsive force to a vehicle, a command value calculation unit ( 109 ) for calculating a command value for a drive source of the vehicle based on the drive manipulated variable, a propulsive force control unit ( 115 ) for controlling the propulsive force based on the command value, operating state detection units ( 102, 103 ) for determining the operating states of the drive source, a drive manipulation rate of change calculation unit ( 110 ) for calculating the rate of change in drive manipulation, an operating state rate of change calculation unit ( 111 ) for calculating the rate of change in the operating state, and an abnormality detection unit ( 112 ) for detecting abnormalities in the drive source based on the rates of change in drive manipulation and the operating state.
1. An onboard control device for controlling a propulsive force of a drive source for driving a vehicle comprising:
a drive manipulation rate of change calculation unit that is configured to calculate the rate of change in drive manipulation that is a rate of change: i) in the drive manipulated variable, or ii) in a calculation value calculated on the basis of the drive manipulated variable;
an operating state rate of change calculation unit that calculates the rate of change in the operating state that is a rate of change: i) in the operating state, or ii) in a calculation value calculated on the basis of the operating state; and
an abnormality detection unit that detects abnormalities in the drive source, based on a difference or a ratio between the rate of change in drive manipulation and the rate of change in the operating state exceeding a predetermined threshold value, when a vehicle acceleration of a predetermined level or more occurs.
