The present disclosure relates to a verification apparatus for a vehicle-mounted control apparatus having a first program processing unit that executes a current program, based on an output of a sensor and outputs a processing result to an actuator unit. Because the verification apparatus has a second program processing unit that executes the current program and outputs a processing result, a third program processing unit that shares the output of the sensor unit with the second program processing unit and that executes a new program and outputs a processing result, and a comparison determination unit that compares the respective outputs, it is made possible to perform a regression test effective for the new program at low cost, without affecting operation of the vehicle-mounted control apparatus.

Vehicle apparatus including verification apparatus

A control system for preventing abnormal operation including the storage of execution time input and output values, the storage of normal time read and write information of an address contained in a pre-defined address range, and the determination of abnormality based on comparison between execution time and normal time information.

Control system

A first processing environment includes: a control processing unit configured to execute control processing on a control subject; a first storage area for storing data for controlling the control subject; and a verification determination unit. A second processing environment includes: a second storage area for storing an expected value; a verification value generation unit; and a verification execution unit. The verification value generation unit generates the verification value before the control processing is stopped. The verification execution unit executes comparison processing of comparing the expected value and the verification value before the control processing is activated. When the comparison result indicates a verification success, the verification determination unit executes determination processing of determining that the control processing is to be activated, and executes determination processing of determining that activation of the control processing is to be stopped when the comparison result indicates a verification failure.

Control device and control method

Provided is a cell capacity adjusting device for reducing fluctuations in state of charge (SOC) among cells of a battery pack, which is formed by connecting a plurality of cells-in series, during suspension of operation of electrically-powered equipment whose main power source is the battery pack. From among the plurality of cells-, one or a plurality of cells having a voltage value equal to or higher than a cell capacity adjustment target voltage are selected. By the selected cells, an intermittent operation unit, which operates even during the suspension of operation of the electrically-powered equipment, is caused to perform an intermittent operation. Through repetition of the intermittent operation, voltage values of the selected cells are decreased. Thus, fluctuations in state of charge (SOC) among cells are reduced without unnecessarily discharging battery stored energy of the battery pack

Cell capacity adjusting device

Provided is an electrically driven vehicle () loaded with a driving storage battery () charged by electric power supplied from a power supply outside the vehicle, including an occupant detection sensor () for detecting whether or not an occupant is in the electrically driven vehicle (), rotation sensors () for detecting presence/absence of rotations of wheels () provided to the electrically driven vehicle (), and a charge control unit () for determining whether or not a state in which the occupant detection sensor () detects that the occupant is not in the electrically driven vehicle () and the wheel rotation sensors () detect that the wheels () are not rotating has continued for a predetermined period, and starting, when the charge control unit () determines that the state has continued for the predetermined period, the charge of the driving storage battery ().
