  • Patent number: 11719333
    Abstract: A load drive system, capable of providing certainty about instructions transmitted from a load control device to a load drive device as well as suppressing an increase of processing load, includes an ECU, a drive device, a communication bus to which the ECU and the drive device are connected, and a third signal line different from the communication bus connecting the ECU and the drive device. The ECU generates a frame including a drive instruction message, and transmits the message to the drive device via the communication bus. The drive device receives the frame via the communication bus, and extracts the drive instruction message from data of data field in the received frame. The drive device converts the drive instruction message into a load drive signal, and notifies the converted load drive signal to the ECU via the third signal line.

  • Patent number: 11439028
    Abstract: A vehicle control apparatus is disposed inside a housing for accommodating a transmission. The vehicle control apparatus includes a metal base, a resin case, a printed circuit board on which an electronic component mounts, an oil-tight seal member, and a breathable filter. The metal base is made of metal. The resin case is attached to the metal base to form an interior space. The resin case includes a part having a connector penetrating inside and outside of the housing. The printed circuit board is disposed in the interior space. The oil-tight seal member is placed between the metal base and the resin case to surround the printed circuit board. The connector has a ventilation hole. The breathable filter is disposed at a location where the ventilation hole faces outside.

  • Publication number: 20220063523
    Abstract: A drive device includes a driver, a determination storage, a comparator, and at least one of a control storage and a monitor storage. The control storage stores a control pattern that includes a signal instructing a conduction state of each of loads. The driver control semiconductor switches respectively corresponding to the loads according to the control pattern. The determination storage stores a determination pattern. The monitor storage stores a monitor pattern that is a result of monitoring the conduction state of each of the loads. The comparator compares the determination pattern with a comparison pattern that is at least one of the control pattern and the monitor pattern, and determine that an abnormality of the comparison pattern has occurred in response to that the determination pattern and the comparison pattern satisfy a predetermined correspondence relationship.
