SYSTEM AND METHOD FOR SIMULATING VEHICLE ENGINE SOUNDS
The invention relates to the technologies used in simulating the sounds reproduced by the exhaust system or the burnt gas exhaust system of a vehicle engine. Method of simulating the vehicle engine sounds reproduced by the burnt gas exhaust, characterized in that the recorded or synthesized sound templates are loaded into the electronic control unit located in the vehicle and connected to its CAN circuits, and the recorded sound templates (modified depending on the CAN circuits information) are reproduced through at least one speaker that is part of the acoustic device connected with the electronic control unit. Also, a system for simulating the vehicle engine sounds reproduced by the burnt gas exhaust system is described. The technical result consists in providing high accuracy in generating and simulating of specific vehicle engine sounds reproduced by the burnt gas exhaust system.
CONTROL APPARATUS FOR ELECTRIC MOTOR AND VEHICLE
A control apparatus includes: a rotor temperature estimation unit estimating a temperature of a rotor based on stator temperature information from a first temperature sensor for identifying a temperature of a stator, refrigerant temperature information from a second temperature sensor for identifying a temperature of refrigerant used to cool an electric motor, and rotation speed information about the rotor from a resolver for identifying a rotation speed of the rotor; and an electric motor control unit controlling at least one of an output characteristic and a drive condition of the electric motor based on the temperature of the rotor estimated by the rotor temperature estimation unit.

ON-VEHICLE DEVICE AND COMMUNICATION SYSTEM
An abnormality of a component can be accurately detected.
An on-vehicle device is an on-vehicle device that is mounted on a vehicle to communicate with a server. The on-vehicle device includes a first information generation unit that generates first information which is information on a state of a first component mounted on the vehicle by using an output of a sensor mounted on the vehicle, and an out-vehicle communication unit that transmits, to the server, the first information and second information which is information on a state of a second component which is a component different from the first component, and receives, from the server, a state signal indicating an abnormal state of the first component calculated by the server based on the first information and the second information.
CONTROL LOOP FOR NAVIGATING A VEHICLE
A system for navigating a vehicle may include a processor programmed to receive an output provided by a vehicle sensor, and determine a navigational maneuver for the vehicle along a road segment based on the output provided by the vehicle sensor. The processor may also be programmed to determine a yaw rate command and a speed command for implementing the navigational maneuver. The processor may also be programmed to determine a first vehicle steering angle based on the yaw rate and speed commands using a first control subsystem, and determine a second vehicle steering angle based on the yaw rate and speed commands using a second control subsystem. The processor may further be programmed to determine an overall steering command for the vehicle based on a combination of the first and second steering angles, and cause an actuator associated with the vehicle to implement the overall steering command.

Methods and Apparatuses for Supporting Vehicle-to-Infrastructure Communication
A method including determining a direct distance between the vehicle position and a position of the roadside unit and a planar distance between the vehicle position in a horizontal plane containing the vehicle position, and a projection of the position of the roadside unit onto the plane. The method further includes calculating a height of a roadside unit relative to the vehicle position using the direct distance and the planar distance determined for the vehicle position. The method also includes setting a value indicative of the height of the roadside unit relative to the vehicle position as a height correction value and storing the height correction value of the vehicle position in association with information indicative of the vehicle position as the height correction function.

VEHICLE CONTROL DEVICE, VEHICLE, VEHICLE CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
A vehicle control device is mountable on a vehicle. The vehicle control device includes: a processor; and a memory storing instructions that, when executed by the processor, cause the vehicle control device to perform operations. The operations includes: acquiring detection information obtained by detecting an obstacle around the vehicle; performing collision determination of evaluating a possibility of collision with the obstacle, generating, based on the detection information, information on an approaching object that is an obstacle approaching the vehicle and information on a detection point group that is a set of detection points indicating an obstacle that does not move; and excluding the approaching object from collision determination in a case in which the detection point group has a shielding effect of shielding the vehicle from the approaching object. The shielding effect is evaluated by using a gap threshold that is set based on a vehicle width.
