The invention discloses a strain gauge type force sensor, a braking system and a vehicle, and aims to improve the detection precision of the force sensor and further improve the braking safety of the vehicle. The strain gauge type force sensor comprises an elastic base and one or more strain gauges, the elastic base comprises a first surface and a second surface, the first surface and the second surface are arranged back to back along the axial direction of the elastic base, the first surface is used for receiving measured pressure, the second surface is used for fixing the one or more strain gauges, the first surface comprises an inclined surface area, and the inclined surface area is used for receiving the measured pressure. The slope area of the first surface is annularly distributed in the circumferential direction of the elastic base, and the slope area of the first surface gradually inclines towards the direction close to the second surface in the direction away from the axis of the elastic base. The second surface comprises an inclined surface area, the inclined surface area of the second surface is annularly distributed in the circumferential direction of the elastic base, and the inclined surface area of the second surface gradually inclines in the direction away from the first surface in the direction away from the axis of the elastic base.
