PROBLEM TO BE SOLVED: To provide a switching element driving device that is capable of appropriately detecting a situation where an abnormality occurs to an active gate control function.SOLUTION: Prior to normal control of a motor generator, a drive control part 36 performs processing to ON-operate a constant current switching element 28 and a first discharge switching element 32a and OFF-operate a second discharge switching element 32b. Then, when it is determined that a logic of a second determination signal Sig2 inputted into an abnormality determination part 50 is "H", abnormality determination processing is performed to determine that an open abnormality or a short abnormality occurs to a first discharge resistor 30a, a short abnormality occurs to the first discharge switching element 32a, an open abnormality occurs to a part, which is from the first discharge resistor 30a to a terminal T4, of a first discharge path Lda, or an open abnormality occurs to a part, which is from the terminal T4 to an emitter, of the first discharge path Lda. |
