Abstract:
1. A four-wheel vehicle comprising: a front wheel and a rear wheel each provided with an in-wheel motor, wherein an angle between an instantaneous rotation center of the front wheel and a front wheel contact patch is approximately the same as an angle between an instantaneous rotation center of the rear wheel and a rear wheel contact patch, and a relation between a change in a kingpin offset and a change in a wheel stroke for at least one of the front wheel and the rear wheel is such that a proportion of a ratio of the change in the kingpin offset to the change in the wheel stroke for the front wheel to a ratio of the change in the kingpin offset to the change in the wheel stroke for the rear wheel is determined to be greater than a distribution ratio of a braking force for the front wheel relative to a distribution ratio of a braking force for the rear wheel of the four-wheel vehicle in braking.
