[0030] The working principle of the embodiment is as follows:

[0031] The terrain analysis system of the intelligent travel baby stroller can analyze the terrain of the road currently traveled by the vehicle, and the principle is that the ultrasonic emitter 300 located in front of the vehicle body 200 emits ultrasonic waves, the ultrasonic sensing system senses the reflected ultrasonic waves and analyzes them, so as to realize the identification of the terrain, if the front road surface is not large in ups and downs and can be crossed, the shock absorption structure of the vehicle body 200 is used to pass through, for example, when the first rolling member 131 passes through the protrusion, the second rolling member 141 is driven to be pressed down, at this time, the second rolling member 141 and the third rolling member 151 simultaneously support the ground, the second buffer member 142 and the third buffer member 152 simultaneously buffer the vehicle body 200, when the first rolling member 131 completely passes through the protrusion, the first rolling wheel 131b, the second rolling wheel 141b and the third rolling wheel 151b restore the state of rolling on the same horizontal plane, when the second rolling member 141 passes through the protrusion, the second rolling member 141 is lifted, the first buffer member 132 is compressed, the first rolling member 131 and the third rolling member 151 simultaneously support the ground, the first buffer member 132 and the third buffer member 152 simultaneously buffer the vehicle body 200, when the third rolling member 151 passes through the protrusion, the first rolling member 131 and the second rolling member 141 support the vehicle body 200, therefore, no matter which rolling wheel passes through the uneven place, at least four rolling members support the ground, four buffer members buffer the vehicle body 200, the shock absorption effect is better, the lifting amplitude of the vehicle body 200 is smaller, the vehicle body 200 is more stable, the influence of road bumps on the baby is reduced, and a more stable and comfortable driving experience is provided for the baby;

When the road in front is relatively flat, the rotating speed is appropriately increased to speed up the passing. When the ultrasonic sensing system identifies that an obstacle that cannot be crossed is encountered in front, the first control module starts the brake module to speed up the deceleration process of the vehicle.
