A vehicle control device include a processor. The processor is configured to monitor a primary power source and a secondary power source for anomalies, the primary power source and the secondary power source supplying electrical power to a plurality of drive devices configured to control deceleration and steering of a vehicle, and in a case in which an anomaly has been detected in at least one of the primary power source or the secondary power source as a result of the monitoring, control the vehicle by supplying electrical power to a drive device having a lower electrical power consumption amount among the plurality of drive devices.

Vehicle control device, vehicle, vehicle control method, and storage medium storing control program

A structure and method for enabling a passive vehicle occupant restraint to be activated at the earliest possible timing, irrespective of a type of a collision. A floor sensor measures a deceleration G applied to the length of a vehicle and outputs the deceleration as the measurement G. An arithmetic unit carries out a predetermined arithmetic operation on the measurement G output from the floor sensor, so as to determine a function f(G). A conditional activation unit has a variation pattern of a threshold value T that varies with a variation in velocity v of a non-stationary object. The conditional activation unit reads a threshold value T corresponding to an input velocity v from the variation pattern and compares the threshold value T with the value of the function f(G). In case that the value of the function f(G) exceeds the threshold value T, an activation signal A is input to a driving circuit. A satellite sensor outputs an ON signal when a deceleration of not less than a predetermined reference value is applied to the vehicle. A threshold variation pattern selection unit changes the variation pattern of the threshold value T against the velocity v used in the conditional activation unit to another variation pattern, in response to the ON signal output from the satellite sensor.

Activation control apparatus for passive vehicle occupant restraint and method of controlling activation of passive vehicle occupant restraint

A floor sensor,measures a deceleration G applied to the length of a vehicle and outputs the deceleration as the measurement G. An arithmetic unit,carries out a predetermined arithmetic operation on the measurement G output from the floor sensor,, so as to determine a function f(G). A conditional activation unit,has a variation pattern of a threshold value T that varies with a variation in velocity v of a non-stationary object. The conditional activation unit,reads a threshold value T corresponding to an input velocity v from the variation pattern and compares the threshold value T with the value of the function f(G). In case that the value of the function f(G) exceeds the threshold value T, an activation signal A is input to a driving circuit,. A satellite sensor 30 outputs an ON signal when a deceleration of not less than a predetermined reference value is applied to the vehicle. A threshold variation pattern changing unit,changes the variation pattern of the threshold value T against the velocity v used in the conditional activation unit,to another variation pattern, in response to the ON signal output from the satellite sensor,. This structure of the present invention enables a passive vehicle occupant restraint to be activated at the earliest possible timing, irrespective of a type of a collision, in which the vehicle crashes.
