  • Publication number: 20220405087
    Abstract: Provided is a vehicle control device that ensures normal control even when a program including an error is distributed. A vehicle control device includes a calculation unit and a memory, and updates software stored in the memory, and the vehicle control device includes a communication unit which receives encrypted software, a decrypting unit which decrypts the encrypted software into a plaintext, a rewriting unit which is set in the memory and stores the decrypted software, and a determination unit which collates first collation information set in advance in the memory, second collation information given to the software, and the first collation information, determines whether or not to store the decrypted software based on a collation result, and selects the decrypted software as software for next activation when the decrypted software is stored.

  • Patent number: 6972710
    Abstract: In an automotive radio wave radar, a center frequency of a transmitted wave is shifted at a certain cycle, and position information of an obstacle detected at three or more center frequencies is subjected to decision by majority to determine whether detection results of the obstacle are erroneous with the occurrence of jamming. If any of the detection results is determined to be abnormal, the abnormal result is discarded. An automotive radio wave radar is realized which can correctly perform the obstacle detection even in the event of jamming without causing erroneous obstacle detection or omission of the detection.
