Abstract

An electronic control unit for a vehicle is diclosed. According to the disclosure, the electronic control unit for the vehicle comprises a circuit substrate (1), a resin sealing member (2), a transmitting memebr (3) and fastening members (4). The circuit substrate comprises a substrate member (11) including fastening portions (111) fastened to an object to be fastened, and a behavior detection sensor (12) disposed at the substrate member to detect behaviors of the vehicle. The resin sealing member is in contact with the circuit substrate and covers the circuit substrate except the fastening portions, so that the fastening portions are exposed from the resin sealing member. The transmitting memebr has fixing portions (31) to be fixed to the vihicle and substrate fastening portions (32) abutted against the fastening portions. The transmitting memebr transmits the behaviors of the vehicle to the circuit substrate. The fastening members are abutted against the fastening portions to fasten the circuit substrate to the transmitting memebr. The transmitting memebr is provided with a covering portion (33) at least covering a portion of an outer surface of the resin sealing member.

Description

technical field [0001] The present disclosure relates to an electronic control unit for a vehicle mounted to the vehicle. Background technique [0002] The vehicle is provided with an electronic control unit that detects the behavior of the vehicle and performs various controls based on the detection result. The behavior of the vehicle is referred to as vehicle behavior. For example, an airbag ECU can be used as an electronic control unit. Since water ingress into the electronic control unit may occur according to water from an air conditioner or by water used to wash the interior of a vehicle, the circuit substrate with electronic parts needs to be waterproof. [0003] JP-2010-40992A discloses an electronic control unit in which a circuit substrate is covered by resin sealing (resin molding). Therefore, the circuit substrate can be waterproofed. [0004] Regarding the electronic control unit mounted to the vehicle behavior sensor, it is necessary to accurately transmit ...
