  • Publication number: 20180233920
    Abstract: In a solar power generation control device, a memory stores an output voltage at which maximum power is obtained, for each illuminance on a panel surface of a solar panel, acquisition circuitry acquires a vehicle speed, a present illuminance on the panel surface, and first information indicating an illuminance in a prescribed area ahead of a vehicle, and calculation circuitry calculates a predicted illuminance on the panel surface, which is an illuminance after a lapse of a prescribed length of time, based on the first information and the vehicle speed. When determining that an absolute value of a difference between first and second output voltages, at which maximum powers are obtained respectively at the present and predicted illuminances, exceeds a prescribed threshold, control circuitry makes correction such that an output voltage of the solar panel coincides with the second output voltage upon the lapse of the prescribed length of time.

  • Patent number: 10049232
    Abstract: A rewrite detection system, a rewrite detection device and an information processing device can detect unauthorized rewrite to a program or data stored in a storage unit of the information processing device. A rewrite detection device generates a random seed and transmits it to an ECU and a server device. The ECU calculates a hash value using a predetermined hash function on the basis of the received random seed and the storage content of the storage unit, and transmits the hash value to the rewrite detection device. The server device transmits an expectation in response to an inquiry from the rewrite detection device. The rewrite detection device determines whether unauthorized rewrite to a program or data in the ECU has been performed or not in accordance with whether the expectation received from the server device and the hash value received from the ECU coincide with each other or not.

  • Patent number: 10027672
    Abstract: An access restriction device as well as an on-board communication system and a method for communication restriction, which prevent outside leakage of information caused by unauthorized access of malicious programs to an in-car network. The communication between the in-car network of the vehicle and an external device is performed by a security controller. The security controller can perform addition or update of a program involving processing for transmission and reception of the information. The security controller performs processing for restricting access to information of the in-car network performed by program execution according to an access authorization level of each program and an access permission level of each type of information. The security controller restricts the transmission depending on the access authorization level of each program and the access permission level of each type of information in case of transmitting the information to the in-car network by the program execution.

  • Patent number: 10001104
    Abstract: A control apparatus for an internal combustion engine is provided which works to control an electric motor to start the engine through a belt transmission system. The control apparatus restricts rotation of the electric motor so as to keep a speed of the electric motor below a speed at which the electric motor is capable of producing a maximum torque until a given period of time passes since the electric motor is actuated to start in the motor mode. This enables the electric motor to generate the maximum torque when it is required to crank the engine.

  • Patent number: 9903443
    Abstract: An eccentric speed variator includes a first rotor, a second rotor, a third rotor, a cylindrical pin, and a flange. The second rotor has a hole formed therein. The third rotor rotates eccentrically to change a relative rotation phase between the first and second rotors. The cylindrical pin extends through the hole of the second rotor to establish mechanical engagement between the second and third rotors. The flange is secured to or integrally formed with an end of the cylindrical pin. In operation, when the flange contacts the outside wall of the second rotor, it serves to minimize inclination of the third rotor relative to the second rotor, thereby reducing local friction between the second and third rotors to eliminate undesirable mechanical vibration or noise. This structure also enables parts of the cycloidal speed reducer to be decreased, which leads to a reduced size of the cycloidal speed reducer.

A rewrite detecting device generates a random seed and transmits the random seed to an ECU, the ECU calculates a hash value using a predetermined hash function, and transmits the hash value to a rewrite detecting device. The ECU decides a storage region serving among storage regions of the storage unit, and calculates the hash value. The rewrite detecting device determines whether the hash value received from the ECU is right or wrong, and determines whether or not fraudulent rewrite has been performed. The ECU designates a storage region which is apart from a storage region used as a previous hash value calculation target by a predetermined address as a storage region of a current processing target.
