PROBLEM TO BE SOLVED: To set a threshold value which is effective even when viscosity of working fluid is changed by correcting a threshold value, which is used for comparison with an operation speed detection means of a brake operation member when action of the second braking force generating means is controlled, on the basis of the detection result of a temperature detection means. SOLUTION: A temperature (x) as a detection output of a temperature sensor is compared with a set temperature T deg.C (step 201), and if the temperature (x) is lower than the set temperature T deg.C, low temperature is determined and a threshold value correction ratio is computed from A×(x-T)+1 (step 202), and the computed threshold value correction ratio, which is smaller than 1, and an ideal threshold THo are multiplied together so that the threshold value THo is corrected to a threshold value TH suitable for a low temperature. When the temperature (x) is higher than the set temperature T deg.C, a high temperature is determined and a threshold correction ratio is computed from B×(x-T)+1 (step 203), and the computed threshold value correction ratio, which is larger than l, and the ideal threshold THo are multiplied together so that the threshold value THo is corrected to a threshold value TH suitable for a high temperature. |
