摘要： An object of the present invention is to provide a technology that enables second control software to continue processing using a peripheral circuit even in a situation where an abnormality related to first control software occurs. An electronic control device includes a memory (3) that stores the first control software and the second control software, a CPU (1) that executes the first control software and the second control software, and a peripheral circuit (200) used by the first control software and the second control software. The memory further includes a first buffer (313a) and a second buffer (323a). The CPU interrupts at least one of the processing of storing first peripheral transmission information in the first buffer and the processing of transmitting the first peripheral transmission information to the peripheral in a specific situation in which the abnormality related to the first control software occurs.

摘要： This shock absorber is disposed between a vehicle body and an axle. The shock absorber includes a bottomed cylindrical cylinder, a spring seat, and a mold release rib. The spring seat is formed integrally with the cylinder. The spring seat protrudes in a radial direction of the cylinder from the cylinder to support a suspension spring. The mold release rib is formed integrally with the cylinder and the spring seat. The mold release rib connects an outer circumferential portion of the spring seat and the cylinder. The mold release rib has a face part provided at an outer end portion of the cylinder in the radial direction.

摘要： An electric power steering apparatus according to the present invention includes a first control device that is capable of controlling a first actuator of a steering device, a second control device that is capable of controlling a second actuator of the steering device, and a third control device that is capable of switching connection to, and disconnection from, at least one of the first actuator and the second actuator. When a failure occurs in the first control device, the first control device is disconnected from the first actuator, and the third control device is connected to the first actuator. When a failure occurs in the second control device, the second control device is disconnected from the second actuator, and the third control device is connected to the second actuator. In this way, even when a failure occurs in one of a plurality of control devices, reduction in total output of electric motors can be prevented.

摘要： A steer-by-wire control device according to the present invention includes a control device that controls a first motor that operates a steering wheel of a vehicle and a second motor that controls steering operation of a wheel. Before making a transition to an automatic driving mode of the vehicle, the control device applies input torque to the steering wheel by the first motor in a forward rotation direction and a backward rotation direction of rotation directions of the first motor, acquires behavior information of the steering wheel obtained by application of the input torque, and determines whether or not to estimate a control parameter of the steering wheel based on the behavior information. The behavior information includes at least one of a value of a rotation angle of a steering wheel and a value obtained by time-differentiating a rotation angle.
