摘要： PROBLEM TO BE SOLVED: To provide a vehicular electronic control device that can control a vehicle even if communication with a storage device is stopped.
SOLUTION: An engine speed detection part 110 detects the speed of an engine 400 when necessary. If the speed of the engine 400 is lower than a normal idle speed, or if the engine 400 is in a cranking state and a voltage applied to an EEPROM 200 is lowered, a communication control part 120 maintains stopped communication with the EEPROM 200. When communication with the EEPROM 200 is stopped, a provisional vehicle control part 130 reads out default data in a memory 140 to provide power steering control according to the default data.

摘要： PROBLEM TO BE SOLVED: To provide a brake control device capable of efficiently using power while securing a braking force in brake control when a power supply voltage is lowered.
SOLUTION: In the brake control device of one embodiment, normal brake control is performed if an output voltage of power supply is threshold voltage or higher, and a set braking force and responsiveness are secured. When the output voltage of power supply becomes lower than the threshold voltage, the normal brake control is switched to power saving brake control, and power consumption in the brake control is reduced. When the motor drive of an oil pump is started during the pressure accumulation of an accumulator, the threshold voltage being a switching voltage to the power saving brake control is switched from a reference voltage V10 to a regulated voltage V1x lower than the reference voltage to hardly be shifted to the power saving brake control.

摘要： PROBLEM TO BE SOLVED: To provide a brushless motor drive controller capable of carrying out control to continuously drive a motor even if a short-circuit fault occurs in a switching element for driving the motor. SOLUTION: The controller is used to control the driving of a brushless motor 10 having star-connected exciting coils 11 of three or more phases. The controller includes: a motor drive circuit 20 that has multiple switching elements 21 and sequentially switches the switching elements and thereby controls the vector of a magnetic field generated in the exciting coils to rotationally drive the brushless motor; and a current switching circuit 30 that, when a short-circuit fault occurs in some of the switching elements, carries out current switching control to switch the direction of a current supplied to the motor drive circuit and generates the magnetic field vector in such a direction that it cannot be generated anymore because of the short-circuit fault.

摘要： PROBLEM TO BE SOLVED: To provide a sensor failure determining technology for properly determining a failure of a stroke sensor.SOLUTION: A first monitoring part 102 monitors a first output voltage of a first non-contact stroke sensor 46a. A second monitoring part 104 monitors a second output voltage of a second non-contact stroke sensor 46b. A failure determining part 122 receives a result of monitoring and determines whether a failure occurs in the first stroke sensor 46a or the second stroke sensor 46b. A determination control part 124 controls execution of determination processing of the failure determining part 122. In the first monitoring part 102, an upper limit monitoring voltage V1 to be monitored is set. A first voltage determination part 126 determines whether the first output voltage is likely to reach or exceed the upper limit monitoring voltage V1. When it is affirmative, the determination control part 124 stops determination processing of the failure determining part 122.
