Patent number: 10359823Abstract: 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.Type: GrantFiled: October 10, 2018Date of Patent: July 23, 2019Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Masahiro Asano, Yuriko Nishihara

Patent number: 8605744Abstract: 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.Type: GrantFiled: February 19, 2010Date of Patent: December 10, 2013Assignee: Renesas Electronics CorporationInventors: Masahiro Asano, Yuriko Nishihara
