A driving assistance method, comprising: - a step of detecting a plurality of malfunctions in devices mounted on a vehicle (10,..., 14); - a step of detecting a traveling restriction of the vehicle (10,..., 14); - a step of selecting candidates for a plurality of actions urged on the driver in accordance with the detected plural malfunctions; - a step of choosing a candidate having a higher priority as an action to be urged on the driver from the candidates for the plural actions; - a step of informing a driver of the traveling restriction and the chosen action so as to be urged on the driver, wherein: - when a plurality of traveling restrictions are detected in association with the detected plural malfunctions, the informing step informs the driver of a traveling restriction having a higher priority chosen from the detected plural traveling restrictions, and - the plural traveling restrictions include a state in which vehicle's (10,..., 14) traveling is restricted and a state in which the vehicle (10,..., 14) cannot start up next, - the state in which vehicle's (10,..., 14) traveling is restricted is defined as a maximum speed and a maximum drive force of the vehicle (10,..., 14) are restricted, and - the following steps are comprised: - calculating the maximum speed and the maximum drive force derived from one malfunction, - calculating the maximum speed and maximum drive force derived from the other malfunction among multiple malfunctions, and - choosing, as the candidate with the higher priority, the action corresponding to the malfunction having a lower maximum speed and a lower maximum drive force than the other malfunction. - a step of detecting a plurality of malfunctions in devices mounted on a vehicle (10,..., 14); - a step of detecting a traveling restriction of the vehicle (10,..., 14); - a step of selecting candidates for a plurality of actions urged on the driver in accordance with the detected plural malfunctions; - a step of choosing a candidate having a higher priority as an action to be urged on the driver from the candidates for the plural actions; - a step of informing a driver of the traveling restriction and the chosen action so as to be urged on the driver, - when a plurality of traveling restrictions are detected in association with the detected plural malfunctions, the informing step informs the driver of a traveling restriction having a higher priority chosen from the detected plural traveling restrictions, and - the plural traveling restrictions include a state in which vehicle's (10,..., 14) traveling is restricted and a state in which the vehicle (10,..., 14) cannot start up next, - the state in which vehicle's (10,..., 14) traveling is restricted is defined as a maximum speed and a maximum drive force of the vehicle (10,..., 14) are restricted, and - the following steps are comprised: - calculating the maximum speed and the maximum drive force derived from one malfunction, - calculating the maximum speed and maximum drive force derived from the other malfunction among multiple malfunctions, and - choosing, as the candidate with the higher priority, the action corresponding to the malfunction having a lower maximum speed and a lower maximum drive force than the other malfunction. - calculating the maximum speed and the maximum drive force derived from one malfunction, - calculating the maximum speed and maximum drive force derived from the other malfunction among multiple malfunctions, and - choosing, as the candidate with the higher priority, the action corresponding to the malfunction having a lower maximum speed and a lower maximum drive force than the other malfunction.
