Provided is a brake controlling apparatus, which improves the regeneration efficiency in a constant speed downhill function. The brake controlling apparatus includes a gradient sensor, an operation unit, a brake controlling unit, and a storage unit. The gradient sensor is configured to detect a road gradient. The operation unit is configured to switch a constant speed downhill traveling function to become effective. The brake controlling unit is configured to control first and second regenerating units configured to generate regenerative electric power from braking torques of front and rear wheels, respectively. The storage unit stores an efficiency mapping representing the relationship between the operation of the first regenerating unit and the regeneration efficiency, and the relationship between the operation of the second regenerating unit and the regeneration efficiency. In a case where the constant speed downhill traveling function is caused to become effective, the braking controlling unit calculates the braking torque distribution (S6) of the front and rear wheels in such a way that the comprehensive regeneration efficiency meets the first condition based on the detected road gradient and efficiency mapping, and uses the calculated braking torque distribution to control the first regenerating unit and the second regenerating unit (S8).

    本发明提供一种电动车辆的制动控制装置,其实现定速下坡功能中的再生效率的提高。制动控制装置具备:检测道路坡度的坡度传感器;能够将定速下坡功能切换为有效的操作部;对能够从前轮的制动转矩生成再生电力的第一再生部进行控制并且对能够从后轮的制动转矩生成再生电力的第二再生部进行控制的制动控制部;存储表示第一再生部的动作与再生效率之间的关系、以及第二再生部的动作与再生效率之间的关系的效率映射的存储部。制动控制部在定速下坡功能有效的情况下,基于检测到的道路坡度和效率映射,以使综合的再生效率满足第一条件的方式计算前轮及后轮的制动转矩分配(S6),利用计算出的制动转矩分配来控制第一再生部及第二再生部(S8)。
