• the pitching is particularly likely to occur when the lean vehicle 1 is in a slow-moving state. As described above, the occurrence of pitching can be suppressed by changing the distribution of the braking force generated on the front wheels 2 and the braking force generated on the rear wheels 3 of the lean vehicle 1 based on the speed information of the lean vehicle 1. , can improve the safety of lean vehicle 1.
• the execution unit 32 determines that the speed information is lean when the speed information is information indicating a state in which the lean vehicle 1 travels at a speed lower than the reference speed. Compared to the case where the vehicle 1 runs at a speed higher than the reference speed, the distribution ratio of the braking force to the rear wheels 3 is increased. As a result, in a situation where the speed of the lean vehicle 1 is low, in which pitching due to the large braking force generated in the front wheels 2 is particularly likely to occur, the generation of the large braking force in the front wheels 2 is suppressed to prevent the occurrence of pitching. It can be suppressed appropriately.
