  • Publication number: 20180018011
    Abstract: Power supply of ECUs connected to a communication network is optimally controlled so that power consumption is reduced. A transceiver/receiver converts a message of a differential signal received via a CAN bus into a digital signal. A select circuit determines whether the converted message is in a CAN format or a UART format. If it is in the UART format, the select circuit outputs a message to the UART circuit. A UART circuit determines whether the message matches a UART format. If matched, an ID determination circuit determines whether the input message is specifying a CAN ID of its own ECU. If it is the CAN ID of the ECU, the ID determination circuit outputs an enable signal to turn on a regulator and supply power to an MCU and an actuator.

  • Publication number: 20170356818
    Abstract: A load change detection apparatus is provided with a base member, an elastic member, a first plate, a fixing member and heat flow sensors. The elastic member deforms according to a changed load applied to the elastic member, received by the receiving member. The first plate supports a surface of the elastic member on a side of the base member. The fixing member fixes the lower plate and the elastic member to the base member. The heat flow sensors, provided between the base member and the lower plate, output signals according to heat flowing between the lower plate and the base member. The heat flows due to heat generated or heat absorbed when the elastic member changes the elasticity shape thereof. Stress occurring when the elastic member deforms, is shut off by the first plate, thus direct transmission of the stress to the heat flow sensors is avoided.

  • Patent number: 8688353
    Abstract: An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with a controlled variable arithmetic expression which defines correlations between a plurality of combustion parameters and a plurality of controlled variables of actuators for control of an operation of the engine to calculate a combination of command values to be outputted to the actuators for regulating the controlled variables needed to achieve target values of the combustion parameters. When one of the command values is produced outside an allowable operation range of a corresponding one of the actuators, the engine control apparatus corrects or limits the one of the command values to an upper or a lower limit of the allowable operation range, thereby ensuring the stability in bringing engine output characteristics close to desired values.

  • Patent number: 8649955
    Abstract: An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with at least one of a combustion parameter or a controlled variable arithmetic expression. The combustion parameter arithmetic expression defines combustion conditions of the engine needed to achieve required values of engine output-related values such as exhaust emissions. The controlled variable arithmetic expression defines how to operate actuators for an operation of the engine to meet desired combustion conditions of the engine. The use of the combustion parameter or controlled variable arithmetic expression achieves simultaneous agreement of the engine output-related values with required values without mutual interference between combustion parameters associated with the combustion conditions.

  • Patent number: 8605744
    Abstract: In the upgrading of the ECU, an ECU 1 to be a master notifies other ECUs 1a and 1b of change of an ACK slot length. The ECUs 1a and 1b change the ACK slot length into an ACK slot length received from the ECU 1. At this time, the changed ACK slot length is stored in each register 5a provided in the ECUs 1a and 1b. Subsequently, the master ECU 1 transmits an upgrade data to each of the ECUs 1a and 1b at a communication speed corresponding to the changed ACK slot length. After completion of the upgrade, the ECU 1 notifies of change of the ACK slot length into the original ACK slot length. After receiving this, the ECUs 1a and 1b reset the ACK slot length to the notified original ACK slot length.
