1. A braking control device for a vehicle comprising:
a first sensor configured to detect a first detected value of a first physical quantity that indicates a vehicle state and is used so as to calculate a target deceleration of the vehicle;
a second sensor configured to detect a second detected value of the first physical quantity or of a second physical quantity that is related to the first physical quantity;
a malfunction detector configured to detect a malfunction of the first sensor;
a memory configured to store the first detected value detected by the first sensor and the second detected value detected by the second sensor;
a first calculator configured to calculate a first calculated value from the first detected value and the second detected value stored in the memory, the first calculated value is for calculating the target deceleration before a malfunction is detected by the malfunction detector;
a second calculator configured to calculate a second calculated value from the first calculated value calculated by the first calculator and the second detected value detected by the second sensor, the second calculated value is for calculating the target deceleration at or after the malfunction is detected by the malfunction detector; and
a target deceleration setting circuit sets the target deceleration from the first calculated value calculated by the first calculator while the malfunction is not detected by the malfunction detector, and the target deceleration setting circuit sets the target deceleration from the second calculated value calculated by the second calculator while the malfunction is detected by the malfunction detector.
