摘要： Provided is a drive source control device that can suppress increase in the rotation speed of a drive source. This drive source control device (67) includes: an overspeed determination module (68) to determine whether the rotation speed of each of two drive sources (2L, 2R) is overspeed; and a correction module (69) to, when the overspeed determination module (68) determines that the rotation speed of at least one of the drive sources is overspeed, correct command values for outputs of the two drive sources, supplied from a command module (66a). The correction module (69) corrects the command values of the outputs of the two drive sources (2L, 2R) so that the torque of the drive wheel having greater rotation speed decreases from the torque before the correction, and the torque of the drive wheel having smaller rotation speed maintains or decreases from the torque before the correction.

摘要： The vehicle turning control device for a vehicle includes a first road surface frictional coefficient calculator (22), a second road surface frictional coefficient calculator (25), a control gain calculator (23), a target yaw rate calculator (21), a target yaw rate corrector (27), a first braking/driving force calculator (24), and a second braking/driving force calculator (28). A second road surface frictional coefficient µ2 is obtained without braking/driving forces for respective wheels (2) being taken into consideration, and thus has a magnitude smaller than or equal to the magnitude of a first road surface frictional coefficient µ1. A braking/driving force command value calculator (29) calculates a braking/driving force command value from a braking/driving force (FA) and a braking/driving force (FB) which are respectively calculated with use of the first and second road surface frictional coefficients µ1 and µ2.

摘要： A slip control device for an electric vehicle which errorlessly determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculator 21 calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator 22 differentiates a detection value from a rotation angle sensor 3a twice to calculate an angular acceleration. A slip determination 23 determines whether a wheel 7 driven by a motor 3 has slipped, and a torque limitation 25 limits a torque when determining a slippage. The determination 23 compares the calculated acceleration to the threshold, counts a number of times it is consecutively determined that the calculated acceleration exceeds the threshold, and determines a slippage if the number of times has reached a set value.

摘要： Included are an elastic support mechanism (10) and a shock absorber (11) in a suspension (3) interposed between an in-wheel motor device (1) and a vehicle body structure (2). The elastic support mechanism (10) can change a modulus of elasticity and the shock absorber (11) can change a damping force. The provision is made of a resonance monitoring unit (21) to monitor whether or not a rotational speed of a motor (7) falls within a predetermined resonance frequency range. When the rotational speed of the motor (7) is determined as falling within the resonance frequency range, an elastic modulus control unit (22) changes the modulus of elasticity, and a damping force control unit (23) changes the damping force of the shock absorber (11).

摘要： A slip control device for an electric automobile which assuredly eliminates a slippage with a simple configuration without involving a wasted decrease in running performance, is provided. A maximum rotation frequency calculator 22 calculates a drive wheel maximum rotation frequency Nmax on the basis of a rotation frequency N1 of a driven wheel and an ideal slip ratio λmin according to the following formula, (Nmax - -N1)/N1 = λmin. It is determined whether a drive wheel rotation frequency N2 exceeds the frequency Nmax. If it is determined that the frequency N2 exceeds the frequency Nmax, a torque command value to a motor unit 3 is made to be zero.
