Title: Travel motion control equipment for electric vehicle
Inventor: HAKE MOTOMU
IPC: B60L15/20
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To generate a regenerative brake force as required according to situation. SOLUTION: A regenerative brake force RB corresponding to a vehicle speed is determined (S2), with an accelerator and a brake pedal off (S10), a real deceleration is calculated (S16) from a gravity sensor, and if the real deceleration is within a target range (S18, S20), then RB is supplied (S22) as it is to a system controller. If the real deceleration exceeds (S18) the upper limit value of the target range, then RB is reduced (S24) by Δ RB. If this RB is smaller than 0, then S26 sets RB to zero (S28). If RB is larger than 0 (S26), then S22 is executed by RB as it is, an the step is returned to S10. If the real deceleration is smaller than the lower limit value of the target range (S20), then RB is increased just by ΔRB (S30).  If this RB is larger than the maximum value MAX (S32), then RB is made to MAX (S34) and if the real deceleration is smaller (S32) than MAX, then S22 is executed with RB as it is, and the step returns to S10.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a resonance converter which can operate very efficiently in a wide range of load and can attain a low electromagnetic interference and strict output voltage control. SOLUTION: A low-power auxiliary circuit 12, 14 is installed for each half bridge of a circuit which is formed with main switching elements Q1-Q4 of a resonance converter.

Under a light load, a phase shift is generated between corresponding main and auxiliary switching elements and the current in an auxiliary resonance inductor is increased to a sufficiently high level for zero-voltage switching of all the switching elements in the bridge by the sum of the currents in the main resonance inductor and in the corresponding auxiliary resonance inductor.
