Abstract: Provided is a solenoid valve control device capable of detecting a motion of a valve body in response to a drive command without adding a special circuit.
According to the present invention, a solenoid valve control device controls opening and closing of a solenoid valve in an internal combustion engine system including: a fuel pump including a plunger that that increases or decreases a volume of a pressurizing chamber by moving up and down with rotation of a pump drive cam, a solenoid valve for sucking fuel into the pressurizing chamber, and a discharge valve for discharging fuel in the pressurizing chamber; and a fuel rail (common rail) that accumulates fuel discharged by the fuel pump. The solenoid valve control device includes a control unit that determines whether or not closing of the solenoid valve has succeeded based on fuel pressure 604 of the fuel rail, or calculates a discharge amount by closing the solenoid valve based on the fuel pressure of the fuel rail.-

Abstract: An object of the present invention is to provide a technique that enables a driver to approve transmission of vehicle data to a data center. The information system includes a first device (101-a) mounted in a vehicle, a second device (102-a) operated by a driver, and a third device (103). The first device classifies the vehicle data into the first data and the second data according to preset classification conditions. The first data is data for which an approval operation by the driver is requested. The second data is data for which the approval operation by the driver is not requested. The first device transmits the first data to the second device and transmits the second data to the third device. The second device receives the first data from the first device, and transmits the first data to the third device in response to the approval operation by the driver.

A vehicle control device 1 includes peripheral state detection sensors 301 to 304 that detect a peripheral state for a host vehicle, a blind-spot object estimation processing unit 311 that calculates a blind-spot region around the host vehicle based on the detected peripheral state of the host vehicle and a feature amount of map information, and estimates an object existing in the blind-spot region and a behavior trend of the object, and a potential risk map generation unit 309 that generates a region having a potential risk that the host vehicle approaches the object, based on the behavior trend of the object estimated by the blind-spot object estimation processing unit 311. The vehicle control device 1 further includes an automatic driving planning unit 201 that generates a lane-change trajectory from the peripheral state of the host vehicle and the map information, compares the lane-change trajectory with a potential risk map, and determines whether or not lane change of the host vehicle is possible, and a vehicle motion control unit 203 that controls an operation of the host vehicle in accordance with the determination of whether or not the lane change is possible.

Abstract: Provided is a vehicle control device capable of improving safety and availability by determining, in response to a failure of a core, a core to which the software is to be moved, determining whether there is a contention in the timings of execution based on software operations after the software is moved to another core, and making an arbitration when there is a contention. The vehicle control device has a CPU 11 that executes a plurality of tasks in clock-synchronization, the vehicle control device including a failure detecting unit 121 that detects a failure of a core 10 on the CPU 11, and an execution timing arbitration unit 124 that allocates a task having been executed by a failed core 10 to a non-failed core 10. When the task having been executed by the failed core 10 is allocated to the non-failed core 10, the execution timing arbitration unit 124 shifts the execution time slot in a manner making the task being executed by the non-failed core 10 executable, thereby setting time slots in which the plurality of tasks are executable.

Abstract: Provided is a vehicle control device capable of more reliably avoiding a collision between an obstacle and a vehicle or reducing a collision damage by more accurately estimating a type and a risk of the obstacle than a conventional vehicle control device. A vehicle control device 100 is a control device mounted on a vehicle V, and includes a three-dimensional object information generation unit 121, a damage degree map generation unit 122, and a travel control unit 123. The three-dimensional object information generation unit 121 detects an object around the vehicle V and generates three-dimensional object information based on external environment information output from the external sensor V1 mounted on the vehicle V. The damage degree map generation unit 122 generates information on a plurality of split regions obtained by splitting a target region including the object in each of a longitudinal direction and a height direction based on the generated external environment information, and sets damage degrees respectively to the plurality of split regions depending on magnitudes of damage at a time of collision of the vehicle V. The travel control unit 123 controls travel of the vehicle V to minimize a collision damage degree corresponding to the damage degree set in the split region.
