Physijs Three.js - Set maximum velocity on an object

Hi there I am working with a simple box which I'm applying an impulse each frame to get it moving using

character.applyCentralImpulse({x: 1, y: null, z: null});

However I want to restrict it's velocity in a direction so it doesn't just fly off - but I can't figure out a way of doing this as I can't find anything in the documentation.

Is this possible with Physijs?

So it turn out the only way to achieve this is to check on each render the velocity of the object and to limit it manually

        //running right
        if(character.getLinearVelocity().x > 15){
            character.setLinearVelocity({x: 15, y: character.getLinearVelocity().y, z:character.getLinearVelocity().z});
        }
        //running left
        if(character.getLinearVelocity().x < -15){
            character.setLinearVelocity({x: -15, y: character.getLinearVelocity().y, z:character.getLinearVelocity().z});
        }
