A pitch angle control system provided in a vehicle including a brake control unit that controls a front wheel brake and a rear wheel brake, wherein the vehicle includes a front wheel brake inputter and a rear wheel brake inputter operated by a driver, characterized in that the pitch angle control system comprises: a front wheel brake detector configured to detect an operation of the front wheel brake inputter of the vehicle by the driver; a rear wheel brake detector configured to detect an operation of the rear wheel brake inputter of the vehicle by the driver; a target brake force calculator configured to calculate a target brake force required by the driver based on the operation of the front wheel brake inputter detected by the front wheel brake detector and the operation of the rear wheel brake inputter detected by the rear wheel brake detector; a target pitch angle setter configured to set a target pitch angle; a target brake ratio calculator configured to calculate a ratio between a target front wheel brake force to be exerted on a front wheel of the vehicle and a target rear wheel brake force to be exerted on a rear wheel of the vehicle as a target brake ratio such that a pitch angle of the vehicle is a target pitch angle set by the target pitch angle setter; and a unit controller configured to control the brake control unit such that a sum of an actual front wheel brake force actually exerted on the front wheel and an actual rear wheel brake force actually exerted on the rear wheel is the target brake force calculated by the target brake force calculator, and to control the brake control unit such that a ratio between the actual front wheel brake force and the actual rear wheel brake force is the target brake ratio calculated by the target brake ratio calculator. a front wheel brake detector configured to detect an operation of the front wheel brake inputter of the vehicle by the driver; a rear wheel brake detector configured to detect an operation of the rear wheel brake inputter of the vehicle by the driver; a target brake force calculator configured to calculate a target brake force required by the driver based on the operation of the front wheel brake inputter detected by the front wheel brake detector and the operation of the rear wheel brake inputter detected by the rear wheel brake detector; a target pitch angle setter configured to set a target pitch angle; a target brake ratio calculator configured to calculate a ratio between a target front wheel brake force to be exerted on a front wheel of the vehicle and a target rear wheel brake force to be exerted on a rear wheel of the vehicle as a target brake ratio such that a pitch angle of the vehicle is a target pitch angle set by the target pitch angle setter; and a unit controller configured to control the brake control unit such that a sum of an actual front wheel brake force actually exerted on the front wheel and an actual rear wheel brake force actually exerted on the rear wheel is the target brake force calculated by the target brake force calculator, and to control the brake control unit such that a ratio between the actual front wheel brake force and the actual rear wheel brake force is the target brake ratio calculated by the target brake ratio calculator.
